To reproduce: 1-View -> Message Body As -> Plain Text 2-Set forward messages as attachment in preferences 3-Select a Content-Type: multipart/mixed message that is not identified as "HTML" in normal header view 4-Forward the message to a valid email address Actual behavior: 1-message bounces with message: " This message has been rejected because it has a potentially executable attachment "Re: Anaconda grub install options?.eml" This form of attachment has been used by recent viruses or other malware. If you meant to send this file then please package it up as a zip file and resend it." 2-NAICT, it is recipient anti-spam software that causes the bounce due to misidentification of attachment as an executable file Expected behavior: 1-message is not misidentified as executable 2-message does not bounce Note that the recommendation to package up as a zip file cannot work correctly, as SeaMonkey will not save the message to file without either multiplying its size with its own formatting, or deleting headers:

That's usually caused by the ".eml" suffix in the attachment name, which many servers use as a trivial check whether or not to allow an attachment.
> Content-Type: message/rfc822;
> name="Re: Anaconda grub install options?.eml"
You can remove the ".eml" for all messages you compose by resetting the mail.forward_add_extension preference to false.
1. Type about:config into the browser's location bar
2. Confirm the warning
3. Copy-paste or type mail.forward_add_extension into the search bar
4. Double-click on the entry that remains to toggle it to false
Now it should work.
