    Nothing useful yet...

    After further investigation, the error only occurs when I am trying to send an attachment. It has absolutely nothing to do with the message text itself.

    I'm hoping there will be a fix soon, it's getting very difficult having to use other methods to send attachments.

    Encountering this issue as well, no solution yet since we have no access to make these low level changes, but in my case it's due to an update to the software used by our e-mail provider.

    Here's some reference to the issue:

    Hi,

    I followed the steps by changing the Wrap Characters from 65 to to max 132; however, the problem still exists and the email are returned with this msg "message has lines too long for transport".

    I never had this problem in the past and it has come up since yesterday only unexpectedly.

    Pls help.
