CentOS - Apr 2013 - Strange Postfix problem

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.

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,
