I have an e-mail I sent some months ago that couldn't be delivered (destination dead or whatever). Every time I do some e-mail a reminder comes up about this unsent message so I thought I'd try to remove it although I remembered that there is no such option in the menu.

I then decided to remove it from the ~/Outbox/mbox file which I did under SU but now the software is re-sending a lot of other e-mail that were successfully sent.

Questions:
1) How can I stop this re-sending of files that have already be sent?
2) How can I stop this attempt at perpetually trying to send to an unreachable address?
3) Is this e-mail system any good or should I dump it and get something better?

Thank you very much for your help.

How are you connecting to whatever email server? Personally I'd say create another account, move whatever emails you want to save and see if the same issue reoccurs, if it doesn't, remove the old account.

Or you can start from scratch and wipe the whole evolution directory, set it up again and test, most likely just something got corrupted.

Thanks to trickykid. I ended up upgrading to a newer version with yum. I couldn't find a way to solve this problem.
