I'm writing this here (the Mint forum) under the assumption that it's the Mint folks who included Thunderbird. Actually, I don't know where the boundaries are between the Linux kernel, Mint, and Xfce.
I need an email client that does not use mbox. Any email storage system that uses file-per-message methods would be fine, but not Thunderbird (its maildir is not supported and doesn't make proper maildir file names).
The email client doesn't need to be a local server - there will be no other application accessing the mail store.
I tried Claws but there were too many bugs.
I installed Evolution and fiddled with configuration but couldn't discover what type of mail system it uses, so I removed it.
I installed Kmail and fiddled with configuration but couldn't discover what type of mail system it uses. Also, when I tried to get help, it wouldn't get help but instead complained that some kde package was missing.
Thanks for any help you care to give.
