Would this be the bit I should look at: (changed ip and domains)
Nov 14 11:16:45 server1 postfix/qmgr: 7BB69ABE5A2: from=<firstname.lastname@example.org>, size=502, nrcpt=1 (queue active)
Nov 14 11:16:45 server1 postfix/smtp: connect to webserver.mydomain1.co.uk[18.104.22.168]:25: Connection refused
Nov 14 11:16:45 server1 postfix/smtp: 7BB69ABE5A2: to=<email@example.com>, orig_to=<firstname.lastname@example.org>, relay=none, delay=1098, delays=1098/0.02/0.07/0, dsn=4.4.1, status=$
Nov 14 11:17:44 server1 imapd: Connection, ip=[::ffff:127.0.0.1]
I notice that my connection is being refused? The domain I use for ispconfig is also my recipient above - would that make a difference?
also where it says server1 - that is the old name of the server.
When I installed ispconfig I used server1.example.com and afterwards changed it to a proper domain webserver.mydomain1.co.uk.
I used the following commands to change the host and domain.
/etc/hostname, /etc/hosts, /home/admispconfig/ispconfig/lib/config.inc.php and /root/ispconfig/httpd/conf/httpd.conf - Is that OK?
