I am sending emails using powershell and smtp. The email include a csv file as attachment. However, the attachment is being receiving with a base 64 format. How could avoid that?. I need to get the attachment in normal ASCII format

A windows service written in c# using MSGraph SDK v4.35 reads customer emails and downloads their .pdf or .tif/.tiff attachments for import. Some emails are arriving with .p7m attachments which are a multipart smime format which contains attachments as text, coded in Base64. I don't know if these were encrypted emails or just signed but I'm able to parse the content as mime and download the content as relevant image files, however, if I cannot download any image files, I need to notify the customer by email. When I try to forward the message to the customer using this MSGraph call
await graphClient
.Users[theAccount]
.Messages[theMessage.Id]
.Forward(toRecipients, null, comment)
.Request()
.PostAsync();
it fails, with the message
ErrorItemNotFound
Message: The specified object was not found in the store., The process failed to get the correct properties.
If the email has no attachments or standard attachments then it works OK. Is this a bug/unsupported feature, or is there something I can use in the call to make it work?
I tried updating the SDK to v4.44 but it stopped finding emails in certain customers' inboxes.
I have a very strange behaviour in Outlook (web, for Windows or for Mac) when I receive a mail with an attachment.
The email is sent by a backend (Microsoft BizTalk) and Mime properties are set accordingly to set the file name of the attachment.
When the email is received in Outlook for Windows, the attachment name is displayed "body.csv" and when I download it, the name of the file is renamed according to the mime property set by the sender.
In Gmail, the filename of the attachment is displayed successfully.
I don't know if this is a known bug in Outlook or a mistake in the sender code while setting the MIME properties.
I am capturing SMTP packets being transferred when sending an e-mail from my machine.
In the packets I get only filename of the attachment attached to the e-mail and not the complete path of the file.
Is there any way to get complete path (file path on machine) of the attachment?
That is not possible!
When the email is being sent, the attachment has already been read by the email program and only the filename without path is used (primarily just to tell the receiver what to call the attached file). There is nothing in the email itself that needs a path to the file.
If SMTP only allows 7-bit ASCII, how do we send pictures/videos/files via email?
Do we encode these objects as 7-bit ASCII? Or basacally we can't send attachments via SMTP protocol?
Yes, we can attach binary files to email messages and send these using SMTP.
The solution is to use MIME and encode the files. One common encoding used is base64.
I am working on testing internationalization of an email reader application. As such I'd like to have a bank of emails with unusual subject encodings and the like to test with. I have been successful at identifying some emails with the headers endoded in specific encodings I would like to test, however I'm not sure how to successfully get the emails into an IMAP account (or alternatively a POP3 account would suffice as well) without butchering the existing headers/encodings.
With Outlook, for example, I can drag and drop messages into the IMAP account from my regular POP3 email account, or use the "resend" feature to send the message to a different account, however, with both of those solutions, outlook re-encodes the headers using it's own choice of encodings. So, for example, instead of the subject being base64 encoded, suddenly it's quoted-printable encoded, and I need it to stay base64 encoded.
So can anyone suggest how to get raw emails imported into an IMAP (or Pop3) account without changing the header encodings for fields such as subject?
Just use some IMAP client, you can store messages to IMAP server.
One free C# IMAP client you can get from:
http://www.lumisoft.ee/lsWWW/download/downloads/Examples/
SotreMessage allows you store raw message to IMAP server.
Also if you have messages in IMAP server and wnat to ttransfer them, you can use IMAP sync application from same link.
If it's just for testing, set up an IMAP server locally, and store the messages on that. Choose some fairly transparent storage so that each message is a file on the server. Don't use an email client to write them, they are just text files (and in particular not Outlook!)
