SquirrelMail merely reports what the IMAP server tells it to. You need to look elsewhere. > Again, we have looked at the mail log, and we are not seeing these > messages anywhere else.

The only way it could be remotely related to SM is if the messages are marked for deletion in one of your mail clients but not expunged. Check your expunge settings in all clients. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
