I've a user who has just reported that when they send to our internal mailman run mailing list they don't receive back a copy of the message they sent.
I know I receive copies of messages I send, and have not had this reported by other users.
We're using 6.0.4 open source edition. The user is accessing mail with the web interface and with Thunderbird/IMAP.
I've checked the mail log and it shows the message being sent from the mailman server, received at the zimbra server and marked as delivered.
Any idea why this isn't showing in the user's mailbox?
