Unable to send mail on CentOS 4.3

[jgao]

Everything works great on FC4. I redo the whole thing on CentOS 4.3. The Scalix seems running fine. But one thing broke. When I tried to send email out using SWA, it gave this error:

Unable to send email to:

There's no problem to use Outlook to connect to the account using POP3 and send and receive emails.

How to diagnose this weird thing?

Thanks.

Not much of an SWA expert, but checking the logfiles in $CATALINA_HOME
& the contents of /var/log/maillog would probably be good start.

Sounds like SWA unable to connect to port 25. Please try to telnet on port 25 from the workstation to the server, e.g. telnet scalixserver 25 should give you something to work with.

The problem is in the file /etc/hosts. There was some extra setting for 127.0.0.1. Fixed it by

127.0.0.1 localhost.localdomain localhost

This is the only change. Weird?

not at all - we need to connect to sendmail running on localhost.FC4 is notorious for butching that up.

Cheers,

Sascha.
