Q: In Thunderbird 2.0, when I forward a message with an attachment of any sort the MIT mail servers bounce it back as an executable. How can I stop this from happening?
Answer
By default, Thunderbird 2.0 will forward messages as an attachment instead of inline in the message. The attachment type it forwards is blocked as an executable file on the MIT mail servers. To prevent this from happening, you can try to do the following:
Windows
Navigate to Thunderbird > Go to Tools > Options > Composing > Change Forward Message from As Attachment to Inline
OS X
Thunderbird > Preferences > Composition > General > Change Forward Message from As Attachment to Inline
