postfix issue after changing server ips

[punchbowl]

Hi,

I recently had to swap server ips. I managed it ok and ran reconfigurator but I've noticed since then that hosted domains are using the old ips. I replaced the ips in main.cf (attached below) thinking that was the issue but it still doesn't work.

Here's a portion of the maillog:

May  9 16:42:26 host courier-imapd: Connection, ip=[::ffff:127.0.0.1]
May  9 16:42:26 host courier-imapd: LOGOUT, ip=[::ffff:127.0.0.1], rcvd=12, sent=365
May  9 16:42:26 host courier-imaps: Connection, ip=[::ffff:127.0.0.1]
May  9 16:42:26 host courier-imaps: LOGOUT, ip=[::ffff:127.0.0.1], rcvd=12, sent=356
May  9 16:42:26 host courier-pop3d: Connection, ip=[::ffff:127.0.0.1]

This problem is: May 9 16:44:23 host postfix/qmgr[17306]: warning: connect to transport private/217.18.71.176-: Connection refused

217.18.71.176 is the old ip that I no longer use.

Any ideas where postfix is getting the wrong ip from?

Thanks in advance.

Make sure that you have proper binding of the IP address in the file /etc/postfix/master.cf

 

[punchbowl]

Hi Igor,

Thanks for the response. In the master.cf I only editted one line where I replaced the old server ip with the new one.

It's the line 4th from the bottom. I didn't touch anything else as I'm not familiar with postfix settings and that was the only obviously wrong thing.

Anything else I can check? Cheers

Also the issue is only affecting shared ips. I have sites with dedicated ips and they don't have the issue at all.

 

[IgorG]

Try to use command:

# postmap -s /var/spool/postfix/plesk/sdd_transport_maps

 

[punchbowl]

yep - all old ips!

Is the a way to rebuild that db or how should I edit it?

Try to rebuild it with
