Changed ISP Address, Now Postfix SMTP Outbox Filling Up

[AceFrahm]

My ISP changed my IP address,
on a box with ISPconfig, Apache, PHP, Drupal, PROftp and Postfix.

I changed the IP in many places according to instructions in other forum posts.
Everything else works,

BUT, now Outlook on my laptop can't send messages thru the SMTP on my server.

Did I miss a setting?

Telnet to port 25 on laptop to the server connects. . . .

Why aren't the messages flowing?

Which error messages do you get in the mail log?

Which distribution are you using?
What's in /etc/postfix/main.cf? What's the output of

netstat -tap

?

Do you use a hostname or the new IP address in Outlook to connect? If you use a hostname, make sure that it already points to the new IP.

My ISPconfig DNS settings

Outlook Setting

It makes no difference whether or not I use the IP, or hostname dns01 or hostname "www".

They all fail to send messages from outlook.

[falko]

Looks good. What's the output of

ls -la /var/lib/postfix

?

[AceFrahm]

root@dns01:/# ls -la /var/lib/postfix
total 12
drwxr-xr-x  2 root root 4096 2007-10-31 17:11 .

-rw-------  1 root root 1024 2008-03-12 23:39 prng_exch

Is this what a non-ISPConfig postfix would look like?
what does prng_exch do?

[falko]

Try

chmod 644 /var/lib/postfix/prng_exch

Does it work then?
