Which pop3 / imap daemon do you use?

If you use courier or dovecot, you will have to activet the maildir checkbox in ISPConfig under management > server > settings on the mail tab.

Does "dig mx me.dyndns.org" points to me.dyndns.org and me.dyndns.org points to your IP address?

hi till,

As perfect_setup_centos_4.3, i use dovecot with actived maildir checkbox

dig point on my ip adresse
dig mx point on me.dyndns.org

Regards

[tesquenure]

hi till,

Is the hostname important at Centos instalation .

I put "server101" instead of "me.dyndns.org"

If it's important how can i change it in CentOS and reflect it in ISPconfig.

Thx

[till]

You can change the hostname of your server in the file: /etc/hostname

Please have a look in your mail.log, if you get any errors there.

Reboot your server afterwards.

Did you create DNS records for myotherserver.com? Can you post the real domain name here?

[tesquenure]

Hi falko,

Apr 25 06:37:48 me postfix/smtp[11809]: 9285B181BF: to=<tesquenure@msn.com>, relay=none, delay=10, status=deferred (Host or domain name not found. Name service error for nam

i think, it's not come from msn the problem ^^ and not from www.myotherserver.com (a product server).

lynx www.msn.com
and
lynx www.myotherserver.com

work find

i think i cant resolve mx on my ISPconf server

why ?, i dont know.

thx

PS :

From my product server www.myotherserver.com if i do
