immediate delete of mails

[Gerald Galster]

Hello,

most imap clients don't delete mails immediately, instead they are marked as deleted and expunged a few days or weeks later.

From Sylpheed docs / Interface tab: https://sylpheed.sraoss.jp/doc/manual/en/sylpheed-8.html

	• If Execute immediately when moving or deleting messages is not selected, a new button appears in the button bar marked Execute. When deleting or moving messages, they are first marked as deleted or moved but Sylpheed does not move or delete them until you press the Execute button (or the Execute entry of the Tools menu).

You could check if the filename of a deleted email has changed in your maildir.

https://wiki2.dovecot.org/MailboxFormat/Maildir  -> Filename examples
Look for T = trashed

This is old and may have been fixed:

Regards,
Gerald
