Outgoing email problem and exim_mainlog not report of errors

Using the webmail (Squirrelmail) to send outgoing email but email never reach by receiver. No problem of receiving email.


I hv check the /var/log/exim_mainlog file it does not show any errors. When I run tail -f /var/log/exim_mainlog to monitor real-time of exims log, outgoing email didn't get into the exim_mainlog file only incoming email get logged. I though the firewall was blocking, but telnet to port 25 to external SMTP host has reply. And runing tcpdump port 25 did not should report outgoing packets when sending emails.. I run two scripts to check the mail permission and alias not sovling the problem either..

Futhermore mail queue report none email inside the queue.

Raw testing...

Email get delived but using webmail not getting through sender. And exim_mainlog loged the above outgoing transaction.

Why using webmail my message did not send to receiver, mailqueue empty and exim_mainlog did not log the outgoing email transaction.?

What should I look next is any other configuations files for exim or imap that I need to checked?

 

Since outlook users can send outgoing email with problems becos of SMTP Auth, so it the SMTP Auth with Squirrelmail not working...
