how to notice if a mail is a forwarded mail? - email

I have a very special problem.
If we create a mail in Outlook, we add a UserProperty which contains a DataBase-ID of our System, so we can Link the mail to the representing DataBase-Item. On the service which reads the mails in each Mailbox and imports them automatically I can read this property by using ExtendedPropertyDefinitions. So far everything is fine...
If the User now forwards the message in Outlook, Olk copies the UserProperty to the new message. And now my problems beginn. Now my Service thinks the new message is also linked to our database and updates DB-Entry with the new Body and new Subject.
So does anyone now how to find out if a message is a forwarded one or how to tell Outlook not to copy the userproperty to the forwarded (new) message?
thx. Jay
What we thought about, but isnt working for our case
- a second userproperty containing a simple tag linke "fromSystem". Cause this would be copied too.
- a second userproperty containing a hashsum calculated from subject and Body. Cause both could be changed by the user. We just create the message, add all properties and Display it. from this Point on we no longer have control what is Happening to the mail until the Service handles it.

Your service consuming EWS should check the ConversationIndex and only update the database if it's 22 bytes long (original source message). Forward emails and reply emails keep appending 5 bytes (10 chars) to the ConversationIndex extending it beyond 22 bytes.
Sample ConversationIndexes

Reply: 01CDD15D80E51C1D4522172840ACA96287DA28A15D970000018630
Forward: 01CDD15D80E51C1D4522172840ACA96287DA28A15D970000018630000000FC30
ConversationIndex represents the sequential ordering of the ConversationTopic (essentially GUID + timestamp). See Working with Conversations on MSDN. ConversationIndex is explicitly defined on MSDN here.
if (message.ConversationIndex.Length == 22)
{
// update DB body, subject, etc.
}
Also make sure you load the EmailMessageSchema.ConversationIndex before trying to access its value.

Multiple To and Cc headers in MIME message sent through LotusScript

I'm building a LotusScript agent looping through a set of documents then - based on a given condition - create mail messages with formatted html text. The recipients will be mostly Non-Notes users (Outlook etc) that's why I want to make sure that subject and message body are formatted correctly. At least one copy is sent to a Domino mail-in database, though.
The code basically creates a MimeEntity, sets "To", "CC" and "Subject" headers then puts a pre-configured message into the mail body and sends it off.
In regards to the body I experimented both with a simple MimeEntity formatted as "text/html" as well as with a multipart message (Content-Type = "multipart/alternative") with 2 child entities (1: "text/plain" without any formatting, 2: "text/html" i.e. html-formatted); in my final code I plan to go for the latter method.
What is really weird is that the recipients (using Outlook as well as other mail clients like Thunderbird) see 3 "To:" and 3 "Cc:" items instead of just one. Looking at the doc in the receiving Domino mail-in database there is only one instance of each item (i.e. SendTo and CopyTo).
Here's the message's source code (taken from Thunderbird) showing those 3 instances of each item:
Return-Path: <sendername#myorg.de>
Received: (removed info here)
Subject: =?UTF-8?B?RWluIGdlbcO8dGxpY2hlcyBzaW1wbGVzIFRlc3RtYWlsIGF1cyBTT1A=?=
MIME-Version: 1.0
Auto-Submitted: auto-generated
To: user1#orgext1.de, user2#orgext2.de
CC: my-mail-in-db#myorg.de
To: user1#orgext1.de, user2#orgext2.de
CC: my-mail-in-db#myorg.de
To: user1#orgext1.de, user2#orgext2.de
CC: my-mail-in-db#myorg.de
Message-ID: <OFBCA50979.C1582837-ONC125856E.00548385-C125856E.0054838A#MYORG.DE>
From: Lothar Mueller <sendername#myorg.de>
This the basic code creating these mails (the simple non-multipart version):
Set docMemo = db.Createdocument()
Call docMemo.Replaceitemvalue("Form", "Memo")
Set nMimeBody = docMemo.Createmimeentity()
'SendTo
Set nMimeHead = nMimeBody.Createheader("To")
Call nMimeHead.Setheaderval("user1#otherorg.de,user2#3rdorg.de")
'CopyTo
Set nMimeHead = nMimeBody.Createheader("CC")
Call nMimeHead.Setheaderval("my-mail-in-db")
'Subject
Set nMimeHead = nMimeBody.Createheader("Subject")
Call nMimeHead.Addvaltext("Subject with ä-ö-ü-ß", "UTF-8")
'html version only for simple non-multipart MIME
Call nStream.Writetext({<p style="font-weight:bold;">Some simple formatted HTML content</p>})
Call nMimeBody.Setcontentfromtext(nStream, {text/html; charset="UTF-8"}, ENC_NONE)
Call nStream.Close()
'finally send
Call docMemo.Send(False)
Now, I can work around this behavior by simply setting the recipients as plain old Notes items, like:
Call docMemo.SendTo = recipientArray
Call docMemo.CopyTo = copyArray
instead of setting those values as MIME headers. In this case there are no more multiple instances of "To" and "CC" items at the recipients' mail clients.
I know that I did this already some years ago in a different project, and back then I didn't have those problems.
Anyone having an idea what could be the cause for this? Could it be due to the Domino version in use (now it's 10.0.1 FP4, back then it was some 9.0.1 version)?
Guess I found the cause for this, at least partially:
As I mentioned in an update to my post this behavior only can be observed when the agent is running in the client as opposed to running on the server:
examining the resulting mail through Ytria's scanEZ I find that there's a difference in regards to the fields that are created:
the run-on-server version just creates the expected fields "To:" and "Cc:" which turn up as "SendTo" and "CopyTo" in the resulting Notes document
If the code is running in the client some more fields are created in the Notes document: in addition to the standard fields there are also "INetSendTo", INetCopyTo, "AltSendTo" and "AltCopyTo". I assume that those extra fields are then rendered by the router to become addition "To:" and "Cc:" header items.
Thanks again to #DaveDelay for bringing up that idea regarding the router and mail.box

change recipient / attach a file to a sent email in outlook

I've been trying to test something out, basically looking to do one of the following things:
Change name of recipient in a sent file. I've tried using Outlook Spy (great tool) but every time I changed the recipient in PR_DISPLAY_TO_W it returned the following error:
Could not edit the property: HrSetOneProp returned MAPL_E_COMPUTED
Attaching a file to a sent email file. (I don't know if this one is possible, but would be useful if it was.)
I appreciate any responses.
PR_DISPLAY_TO / CC / BCC are computed properties. The store provider updates them whenever recipients list is modified.
Use the MailItem.Recipients collection to modify the recipients.
MailItem.Attachments.Add.

Change the sender for an external email in SO_NEW_DOCUMENT_ATT_SEND_API1 function

I'm using SO_NEW_DOCUMENT_ATT_SEND_API1 function to send an email with an attachment both for a sap user and for an external email. So far, so good. I discovered that the sender of these emails is the sap user that fired the report and the function doesn't have the sender exportation parameter like the old SO_DOCUMENT_SEND_API1 has. The problem is that I need the sender to be an external email. I've been searching and couldn't make this happen. Can anyone help or give me an idea? Thanks
As I have already stated in an answer to another question of yours, stop using the old API and use the new BCS API. The documentation contains an example on how to change the sender address:
DATA: lr_send_request TYPE REF TO cl_bcs,
lr_sender TYPE REF TO cl_cam_address_bcs.
lr_sender = cl_cam_address_bcs=>create_internet_address( 'foo.bar#baz.com' ).
lr_send_request->set_sender( lr_sender ).
Just try to copy the example report BCS_EXAMPLE_1 to your local namespace and exchange the line that sets the sender (line 50 in my release, might be a different one on your system).

Identifying where a message was forwarded to

This is one of those hard to explain questions. I've tried my best below, hopefully it is clear what I mean.
Emails are coming in to an address (foo#example.com), and are being forwarded to another email address (bar#subdomain.example.com). The second email address further pipes the email to a simple script, but the script needs to actually know the second email address as it provides meta-data that is crucial to sorting the message (that is, the script gets piped any email sent to *#subdomain.example.com, and it needs to see that it got forwarded to bar#subdomain.example.com in order to correctly process the incoming message).
Originally, I thought that the virtual alias used to forward messages from foo#example.com to bar#subdomain.example.com would update the envelope-to header, but it remains unchanged the same. None of the other headers nor the "received" line reflect that the message was forwarded. My theory is that maybe the pipe instructions for *#subdomain.example.com can be updated to somehow pass the actual address on to the script, but I am not sure how.
For reference, I have included a few examples below:
Headers, after being forwarded:
From sender#example.com Sun Dec 11 19:53:40 2011
Envelope-to: foo#example.com
Received: ...
Subject: Test 6
The valias file for subdomain.example.com (/etc/valiases/subdomain.example.com):
*: "|/home/user/example_script.x.php"
And I answered my own question. It turns out, the recipient is accessible in an environment variable. In my case, since I am using PHP, I can just use the following variable:
$_ENV['RECIPIENT']

Persistence of custom headers within an email thread

I this is probably a strange question, but I thought I'd go ahead and ask. Say, I send an email, using IMAP SMTP, through a special client. This client adds a few custom headers to the email message before sending it on its way. The recipient receives this email and responds to me directly (and maybe CC's a few people as well).
My question is this: Given the above example, would these X-headers persist throughout all the new messages within the thread?
One thing I can think of is the client would be aware of the original email message it sent. All subsequent responses to this email would have a "Reply-To" header whose value equals the "Message-Id" of the previous email. I don't see why I couldn't crawl up these thread of replies until I get to the original message sent by the client, thereby deriving the original custom headers.
Maybe I'm over-thinking this. Any suggestions? :)
A message reply does not necessarily contain anything of the original message. The MUA is likely to suggest a modified (e.g. prepended with "Re:") version of the original subject, and obviously the addresses are utilised for appropriate defaults as well. None of the other content of the message forms part of the reply (unless the sender deliberately includes it, as with quoting or forwarding). Any X- headers that you have in your message will certainly not be included in the reply (unless you have control over that MUA).
However, your plan of tracking the original message is certainly feasible: see Section 3.6.4 of RFC 5322. Every message should (not must) have a Message-ID header, and should have In-Reply-To and References headers when appropriate.
The "Message-ID:" field contains a single unique message identifier. The "References:" and "In-Reply-To:" fields each contain one or more unique message identifiers, optionally separated by [whitespace].
In-Reply-To is mention to identify the message (or messages) that is (are) being replied to, while References identifies the entire thread of conversation. The References header is meant to contain the entire contents of the References header of the message being replied to, so you only need the last message to identify the entire thread.
Note that In-Reply-To and Reply-To are not the same thing (the latter specifies the address that the sender wishes replies to be sent to).
Assuming that you have the original message, then you should be able to use the References header of any reply to identify the original message. Not every MUA will handle References or In-Reply-To correctly, but most will.
As far as I know, there's no reason to think any email client would propagate any header lines it doesn't understand. Most will preserve the subject (usually adding "Re: " if necessary) and derive their "To: " and "Cc: " lines from the previous message's headers, but that's about it. I suppose some (but not all) will generate an "In-Reply-To" line, but that's as far as it goes.
Your idea of having a client crawl back through the thread looking for specific headers sounds like it might be do-able, but you'd have to write your own email client if you want that feature, and you'd still be blocked by the fact that not all email clients preserve message threading in any way.
