ubuntu 10.04 ispconfig3 send/recive problems

[JerseyFresh]

Hello all, im appologize ahead of time but i am new to linux. i am currently switching from M$ sbs03 to ubuntu 10.04 with ISPConfig 3. i cannot send or recive mail through squirrelmail. i use dyndns for Mailhop outbound and inbound also for dynamic dns services. to cut it short i belive the problem may be with the postfix master.cf or main.cf although i cannot be sure the ip is updating correctly. i would be happy to show any configs and any and all help is appreciated.

Any errors in /var/log/mail.log?
Please make sure your MX record points to your public IP. You can check that by running

dig mx yourdomain.com

As you are sending from a dynamic IP, you should set up relaying: http://www.howtoforge.com/postfix_re...her_mailserver

Thanks for the link to the postfix relay howto, they have similar instructions on my mailhop's support site. After much troubleshooting i belive the problem is that the server is not listening on the right ports. i need it to listen on port 10025 for incoming as i use Dyndns.com for my mailhop and backup mx. i know that the relay is working properly as my M$ SBS recieves mail and sends as normal (i shutdown the linux server and started the windows SBS to make sure). This command in particular failed and errored " postmap /etc/postfix/sasl_passwd " i have to try again after some sleep to make sure i entered it correctly though. do you have any reccomendations for an dynamic ip update client (currently using ddclient but dont think its working.

I'd use ddclient as well, but if you are behind a router, you can use your router to update your IP - most routers support DynDNS.org.

What's the output of

netstat -tap

?

It seems as if Postfix isn't running at all. Please try to start it:

/etc/init.d/postfix start
