Message has lines too long for transport error

[Kfardan]

Hi ,

Recently we are facing an error when replying to some emails which is the following:

Subject: Mail delivery failed: returning message to sender

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following

address(es) failed:

 test@domain.com

    message has lines too long for transport

 test@domain.com

    message has lines too long for transport

We tried doing the Auto wrap text at character 65-70.

Still the issue is there

Please advice if anyone know the solution.

I have the same problem

I've been experiencing the same problem with messages on Microsoft Outlook 365 only.  I've changed the value of "Automatically wrap text at character:" to 65 thru 70, as suggested in other forums, but still continue to experience this email error.
