Hello,
Was trying to setup postfix on my home PC. Running Centos 6.4. I don't have a static IP and use zoneedit and ddclient to keep my installation of zoneminder current.
So I decided I wanted to get zoneminder to send me email alerts. Sent some test messages but none were sent.
I went to webdnstools website thinking maybe there is a dns or network problem.
When it checks my dns setup, everything is fine except the mail server is has the wrong IP address. The A record and the www A record have the correct IP. The IP address its reporting is one that belongs to my ISP.
TIA

sounds like your ISP only allows certain services through and intercepts the rest as you do not have a fixed IP. may want to talk to them as they control the DNS and reverse DNS, both of which should be correct for email servers to function correctly. Basically, to do an email server you need a fixed IP.

Consider setting up Postfix to auth (with your ISP email credentials) and send mail through your ISP's mail server. I've seen write-ups for using Gmail in the same way. http://www.cyberciti.biz/faq/postfix-smtp-authentication-for-mail-servers/

Do you need to receive mail or just send it? See the URL above if you just need to send.

This effectively shields your email server from the internet - all mail will appear to come from the ISP's mail IP and thus your dynamic IP will not matter. reception of mail will be by whomever the MX record points to - a fixed IP. you will probably need to use a mail client to retrieve mail from the ISP provided IMAP server.

I will look into that as I just want to send mail.

I kind of suspected that. However, if I go to yougetsignal, port forwarding tester and check ports 25 and 110 for my domain, the ports are open. If I do mail.domain.com, the port is closed.
It sounds as though they are intercepting requests on those ports.
Thanks!!

Greetings,
I saw this sometime ago.
I too have a domain name managed by zoneedit and have ddclient installed in the hopes of having the ip address updated whenever the DSL connection resets.
However so far, I haven't been able to configure ddclient properly to do so. I keep getting the following error message in the /var/log/message file: May 6 18:27:11 leeloo ddclient[2124]: WARNING: file /var/cache/ddclient/ddclient.cache, line 3: Invalid Value for keyword 'ip' = ''
... and haven't been able to figure out how to setup /etc/ddclient.conf
Any chance you could post some guidance?
Thanks,
