I have just installed 5.6U4. The config has amavis with open antivirus and a few other bells and whistles. Port 25 is open and i can communicate directly to the mail server. I can send email to myself locally and directly using telnet.
I have used another server to test sent email and the e-smith server is receiving the mail and issuing confirmation that the mail has been received but is not passing it to the relevent user.
I also can find no trace of the mail in the system and can not find any entry in the mail logs saing that the message has been received.
How ever ROOT receives mail OK so it appears that only the users are effected by this problem
Thanks in advace for any pointers.
