Well, this use to work without any problems but since an upgrade, no one can send email. Using (now) 5.0.10 OSS on SLES10 SP1. Use to run 5.0.9 and we upgraded because of the java error from the admin panel. We also hoped that this upgrade would take care of this problem but it has not. I have added the networks to MTA via the admin panel, 127.0.0.1/32 192.168.1.0/24 188.8.131.52/16. Still no one from 152.16 can send email, they can receive email but not send. I telnet (from 192.168) to the mail server on 25 and am able to send an email. I am not able to telnet from 152.16 as the firewall is under someone elses control. I looked in the /opt/zimbra/log/mailbox.log file and do not see any error related to this. Am i looking in the right place for this error or should it be somewhere else? I would appreciate any help.
/EDIT- We can send from the web interface fine. /EDIT
/EDIT - Again - I searched through messages and mailbox.log and do not even see a SMTP entry. There are 0 postfix entries in the log and the only smtp entries are from the web client. In need of help, please. /EDIT
