Hello,

Our university switched to Office365/Outlook for mail, so I end up sending lots of mail attachments from Gnus to Outlook users.  I have been told by about half a dozen users running Safari that my attachments do not show up for them.  I don't have a Mac, so I cannot easily test this directly, but in the past, I have tested the messages that I am sending with Gnus using tools like https://www.mimevalidator.net/index.html and they were reported as valid.  However, just now I tested some messages again and errors are reported.

Message File: blah.mail
Byteplant MIMEValidator V1.2.5.2
Errors: <LF> linebreak found
(line 1) <LF> linebreak found
(line 2) <LF> linebreak found
(line 3) <LF> linebreak found
(line 4) <LF> linebreak found
(...) parser error: too many bad linebreaks

I am running Gnus from the Emacs master branch, pulled on 2019-03-13.

Has anyone else come across this problem with Outlook/Safari?  Is there a workaround other than the telling these users to fix their broken software (I am guessing that one of Safari or Outlook is the problem)?

Thanks,

Joseph
