I have "When deleting mail" set to "Move to Trash folder" in Usermin, but mail doesn't get moved there. It does create my Trash folder, but it's empty. Running a find on ~/Maildir shows that the files were deleted from the inbox (Maildir/cur/) and not moved to the Trash folder, Maildir/.Trash/...
When I delete a message, it ***actually gets re-sent via SMTP to the original sender***. An email from debian-security-announce@lists.debian.org was actually SENT BACK via SMTP:
Jul 28 19:32:33 server postfix/smtp[2886]: 46F7C31B94: to=, relay=liszt.debian.org[82.195.75.100]:25, delay=613, delays=603/0.04/2.7/7, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 2DA0B13A56C7)
Email notifications about posts followed-up in the Forum got SENT BACK to support@virtualmin.com:
Jul 28 19:23:50 server postfix/smtp[1691]: 4643731BA3: to=, relay=mail.virtualmin.com[70.86.4.226]:25, delay=0.34, delays=0.01/0.05/0.08/0.2, dsn=2.0.0, status=sent (250 Ok: queued as 26CC7290EC7)
There are no errors in the mail log with the Dovecot IMAP server. I also have Horde setup and configured to move email to the Trash folder and it moves fine so I don't think it's the Maildir or folder specifically that's the problem.
What's going on?
