Network Problem in Mail Server

arjuns8471 · 05-09-2008, 05:51 AM

Hi all,

I am using RHEL 4.0 as OS for my Mail Server, using Postfix and Dovecot. My mails are working fine, but the problem is,

Whenever the Server is restarted, the Mail flow is stopped. I cannot ping any machine. Then i have to reconfigure the IP configuraton, means i have to configure it with another ip, restart the service, again configure with the old ip and then restart the service.Then only it will work.

Actually i am using two ip's for my Mail Server, one for incoming mails and another for outgoing purpose. But i have configured one ip only, which we use for incoming mails.

This has been a hectic job for me a we have to configure again and again when there is apower failure or so. What might be the cause of this problem?? Can anyone help??

What actually happens when the machine restarts, what is the output of

Code:

ifconfig

? are the ip addresses there correct ?

How are you ensuring the outbound mail users its specific ip address and inbound its own ?
