i'm using C++ builder 6 and Indy 9/10.
I'm coding to receive certified emails with attachments (basically pdf and xml files).
When i receive the email, it have a TidMessageParts with one multipart/mixed part and others parts for a small text, an xml attachment with info about the certification of the email and parts for digital signature and more.
My problem is: how to open the first part (multipart/mixed) to extract text and attachment in it.
See the answer i'll post.
Thank you.

TIdMessagePart is a TCollectionItem descendant. The TCollectionItem::Collection property points to the owning (parent) TCollection, not to some inner collection, like you are expecting 1. That is why mp1 and mp are pointing at the same address in memory.
You don't "open a message part" in Indy. You simply iterate the TIdMessage::MessageParts collection from one end to the other until you find the particular part you are interested in, such as by looking at their class type, ContentType properties, etc. For example:
TIdMessageParts *mp = MailMessage->MessageParts;
for (int i = mp->Count-1; i > 0; --i)
{
TIdMessagePart *part = mp->Items[i];
if ((TIdAttachment *att = dynamic_cast<TIdAttachment*>(part)) != NULL)
{
...
}
else if ((TIdText *txt = dynamic_cast<TIdText*>(part)) != NULL)
{
if (txt->ContentType = "text/xml")
{
...
}
else if (txt->ContentType = "text/plain")
{
...
}
}
}
1: support for inner nested collections has not been implemented yet, not even in Indy 10. It won't be implemented until Indy 12 at the earliest.
The answer to the problem i posted:
#Remy told me a right observation i was unable to understand well: "The content is parsed and separated into additional collection items as needed."
The email i'm reading is a 'certified email' so the real email is the attachment with .eml extension that indy where reading and i ignored (my email client shows the attachments in the contained email joined with the attachments of the base email).
So, when i have right understood the Remy words and realized where to search the attachments:
i have estracted the .eml file to a folder
added a new TIdMessage component on the form (called PartMessage);
used LoadFromFile method to read the stored file
and now in PartMessage all attachments are visible and i was able to save them as files.
Thanks again to Remy as his words that where preciouses to reach the solution.
P.S. The solution works fine for Indy 9 and 10 with necessary adjustments due to different versions.
P.P.S. i don't know why during my tests i found the text that the email was s/mime encoded as it is not.

I'm making by a requirement a code able to send an E-mail to an specific list of E-mails, due the fact that I must to include the attachments of the record I decided to use an apex class instead an e-mail alert. This object (A custom object ) must populate some fields in an email template with some of the record´s fields. I implemented the following code
Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
mail.setToAddresses(lista);
mail.setTemplateId('00X21000000QR22');
//mail.setWhatId(idMinuta);
mail.setTargetObjectId('005d0000005NMIx');
mail.setSaveAsActivity(false);
List<Messaging.Emailfileattachment> fileAttachments = new List<Messaging.Emailfileattachment>();
for (ContentVersion document: documents)
{
Messaging.Emailfileattachment efa = new Messaging.Emailfileattachment();
efa.setFileName(document.Title);
efa.setBody(document.VersionData);
fileAttachments.add(efa);
}
mail.setFileAttachments(fileAttachments);
Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
I understood that to make the fields merge it´s necesary to use the WhatId method. In the related code, I have commented it because It generates an error (INVALID_ID_FIELD, WhatId is not available for sending emails to UserIds.)
My question is, if is it possible to do this with a custom object. I´m a little confuse with salesforce documentation beacuse it looks like the method supports a custom object, or maybe If I am forggeting something to include in the code.
If i keep the WhatID line commented, effectively the email is sent with the attachments and the Template but it is not populated.
I really need this kind of solution because the org have in this object at least 20 email templates, for me will be easier just to pass the Id of the template instead of makig a code with 20 different html codes for each situation
Thanks a lot

I am trying to send emails using my MVC5 application. To do this, I have installed Mailkit v 1.22.0 through NuGet package manager. And this is how my code looks like:
var FromAddress = "no-reply#email.com";
var FromAddressTitle = "My Org";
var connection = ConfigurationManager.ConnectionStrings["SmtpServer"].ConnectionString;
var Email = new MimeMessage();
Email.From.Add(new MailboxAddress(FromAddressTitle, FromAddress));
var AddressArray = value.SentTo.Split(';');
foreach (var item in AddressArray)
{
Email.To.Add(new MailboxAddress(item));
}
Email.Subject = value.Subject;
Email.Body = new TextPart("html")
{
Text = value.Content
};
using (var client = new SmtpClient())
{
client.Connect(connection);
client.Send(Email);
}
return "Email Successfully Sent";
which works fine except if a wrong recipient Email address has been entered, the application does not detect if the Email was actually sent or not (client.Send(Email) returns void). Is there a way to know if it really ended up getting sent to the recipient or not? If it is not possible with Mailkit, is there any other NuGet package that can do this?
The reason that SmtpClient.Send() returns void is that the SMTP protocol does not specify whether the message gets delivered successfully. All it can do us tell the client that the messages was accepted by the server or not (in which case MailKit will throw an exception).
If you need to know whether the message was successfully delivered, you will need to check for bounce messages sent to you which could take minutes or even hours.
The first thing you'll have to do, however, is subclass SmtpClient and override the GetEnvelopeId and GetDeliveryStatusNotifications methods.
Then, when you receive a bounce message, the top-level MIME part will typically be a multipart/report (represented by a MultipartReport object when using MimeKit). This multipart/report will then contain a message/delivery-status MIME part (and possibly others), which will have a list of header-like fields that specify the details about the delivery status for 1 or more recipients.
MimeKit will parse a lot of this for you (e.g. it has a MessageDeliveryStatus class which contains a StatusGroups property that you will want to use. However, what MimeKit does not do is parse the individual field values (but they shouldn't be that difficult for you to do, typically a few Split(';')'s should be enough iirc for some quick & dirty parsing).
You will want to read the spec for this at https://www.rfc-editor.org/rfc/rfc3464
The MimeKit docs linked above specify which sections to look closely at (I think 2.2 and 2.3).
I would recommend looking specifically at the Original-Recipient and Action fields.
original-recipient-field =
"Original-Recipient" ":" address-type ";" generic-address
generic-address = *text
action-field = "Action" ":" action-value
action-value =
"failed" / "delayed" / "delivered" / "relayed" / "expanded"
You will also need the Original-Envelope-Id field to figure out which message is being reported on:
original-envelope-id-field =
"Original-Envelope-Id" ":" envelope-id
envelope-id = *text
The envelope-id text will be the same string returned by your GetEnvelopeId implementation in the SmtpClient class.
I'm not sure if this is possible, but I need to return an email message from a web api controller. Essentially, it would then allow the user the open the file (an eml or msg), make some changes and then send it to the relevant person.
Code wise I have a service that returns a MailMessage.
I have a controller that returns a pdf, using the file's byte array as it's content, but a mail message doesn't seem the easiest thing to convert.
Is this possible? I would rather not write the message to disk first if I can help it, but I could if this is the only solution.
I have just faced the same problem, and I resolved it like this:
var stream = new MemoryStream(); // this has to contain your file content
var response = new HttpResponseMessage(HttpStatusCode.OK)
{
Content = new ByteArrayContent(stream.GetBuffer())
};
response.Content.Headers.ContentType = new MediaTypeHeaderValue("message/rfc822");
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = "test.eml"
};
If you want to know how to generate emails and do not send the but save them to disk instead, you can check the solution proposed here: How to save MailMessage object to disk as *.eml or *.msg file
I have a form sent by email that travels through different persons like this.
Person A --> Person B --> Person C
I want the person A to be informed when the form is treated by person C. So Person A needs to be in copy of the email sent by person B.
Because person A isn't always the same one, I think the best way to put him/her in copy is to use the "from" field of the email received by person B and to put it in copy.
But how can I find this address with infopath and how can I place it into my email data connection ?
I had this same question today myself and could not find much in the way of answers.
So... I did some work myself and came up with a few solutions.
First I don't believe there is any way to get/set the "From" address using the InfoPath OM. This means you will have to use one of the following options:
No Code:
You will be limited to providing a field on the form where "Person A" can put their email address and use this in the CC. for subsequent stages. That's kind of the only way and while it an extra burden to the user it does have the benefit of providing flexibility.
Code:
Write your own code to send the mail using Outlook Interop or System.Net.Mail and then you will be setting all of the addresses manually anyway.
If you are using AD or something else then you could always get the email address of the current use using System.DirectoryServices.AccountManagement.
Based on an assumption which I cannot find any documentation to back up. That InfoPath uses the account associated with the default store to send email using EmailSubmitConnection. You should be able to use Outlook Interop to find the address that InfoPath will use.
Here is a code sample:
using Outlook = Microsoft.Office.Interop.Outlook;
public string GetDefaultSenderAddress()
{
// This actually opens outlook in the same way as InfoPath does to send the message.
// which can be slow.
string DefaultAddress = string.Empty;
Outlook.Application OutlookApplication = new Outlook.Application();
string DefaultStoreId = OutlookApplication.Session.DefaultStore.StoreID;
foreach (Outlook.Account Account in OutlookApplication.Session.Accounts)
{
if (Account.DeliveryStore.StoreID == DefaultStoreId)
{
DefaultAddress = Account.SmtpAddress;
}
}
// Note you probably won't want to quit if you are about to send the email.
// However I have noticed that this doesn't seem to close Outlook anyway.
OutlookApplication.Quit();
return DefaultAddress;
}
You may have to provide a few more checks in case of different account types etc. But I believe it will work. (I tested it for my scenario and it does).
Note: Of course this opens an outlook instance which you will have to close as well. And it can be slow. Unless outlook is already open in which case it will be very quick. Anyhow when sending from InfoPath Outlook will have to be opened so if you do this just before sending then there should be no noticeable difference.
I would advise using a combination of the no code/with code options so provide a return address which is automatically complete to save the user time. But can be corrected if the user wishes to have the email returned to a different address of if there is a mistake.
Hope that you find that useful.
I get my checking account balance emailed to me once per day. I want to use Google Apps Script to pull the balance from the email message and plug it into my checking account spreadsheet. I am a novice to coding, but so far I have figured out how to do the following, which gets me a log of HTML code of the correct email message:
function myFunction() {
var thread = GmailApp.getUserLabelByName("CHK BAL").getThreads(0,1)[0]; // get first thread in inbox
var message = thread.getMessages()[0]; // get first message
Logger.log(message.getBody()); // log contents of the body
}
However, because this method returns the HTML code for the email message and not the actual message text, it doesn't contain the balance number that shows up in the email itself.
I tried substituting getPlainBody in place of getBody, but it returns a null value in the Log.
The question posted here is pretty much my same question (Google script that find text in my gmail and adds it to a spreadsheet?), but even with Mogsdad's reply and helpful links I haven't been able to figure out what's going wrong.
Can anyone help redirect me on how to get the email content instead of the null value?
(Once that's solved, I can't say that the link on Mogsdad's other reply is very clear about how to identify the currency and copy it into the spreadsheet, but of course I haven't been able to play around yet since I can't even access the content yet.)
Thanks!
EDIT 1
See Serge's answer below for instructions on how to parse the HTML. I used those functions to grab the text of the most recent Bank Account Balance email from a Gmail label/filter and drop it into a cell in my spreadsheet.
Then I was able to use the following equation in an adjacent cell to strip it down to just the currency number:
LEFT(RIGHT(A5,LEN(A5)-FIND("$",A5)),FIND(CHAR(10),RIGHT(A5,LEN(A5)-FIND("$",A5)))-1)+0
Of course, this works for me because the currency number is always preceded by $ (the first, and in my case, only $ to appear in the text) and always followed by CHAR(10). Anyone trying to apply this formula would need similar consistency before and after the value they are seeking to isolate.
You could try this code snippet originally written by Corey G on SO to get the text from the html content. I use it quite often and it works nicely most of the time :) (Thanks Corey)
function getTextFromHtml(html) {
return getTextFromNode(Xml.parse(html, true).getElement());
}
function getTextFromNode(x) {
switch(x.toString()) {
case 'XmlText': return x.toXmlString();
case 'XmlElement': return x.getNodes().map(getTextFromNode).join('');
default: return '';
}
}
And a test function to try it :
function test(){
var html = GmailApp.getInboxThreads()[0].getMessages()[0].getBody();
throw(getTextFromHtml(html));
}
As to why getPlainBody() is returning null, it is most likely due to a bug in Google Apps Script. The issue has been filed at https://code.google.com/p/google-apps-script-issues/issues/detail?id=3980.
From that thread: "It seems the messages affected contain HTML in their content. A possible workaround involves using getBody() instead of getPlainBody() and parsing through the HTML directly."
