Thunderbird attachments and imap

Sometimes my email client (thunderbird) does not download messages properly. They are always the ones with attachments, so I finally (might) have figured out why.

In the config editor, change mail.imap.fetch_by_chunks to false.

Also, when I went to the offending folder's properties and hit "rebuild index" it redownloaded one that it had messed up and it worked out.


Time will tell if that worked, its hard to test. I'll delete this post if the fix is wrong.

I used to have to log into the web based mail for that account, and forward myself the email, which would then download properly, which was weird to me.
