SMTP server "mail.dmzz.biz" is not responding
Posted on 2011-02-22
I have a problem, which I think has a simple solution, but I have been at it for 2 weeks now and I just can't seem to correct it.
I'm running Snow Leopard Server on a Mac Mini v.10.6.6
The server is up and running correctly and for a router I'm using a Time Machine.
as far as the internet and intranet all is working correctly. On the Time Machine I have port 25(SMTP) 110(POP) & 143(IMAP) open, but when I try to setup any e-mail client or on my iPhone I get an SMTP server "mail.dmzz.biz" is not responding or sometimes an POP server "mail.dmzz.biz" is not responding. I have rebuild my DNS, rebuild Open Directory, my ISP created a PRT Record to point to my static IP address which I can check on MXTOOLBOX.com.
Network Solutions is hosting my domain and I created an A Record to point to my static IP as
mail.dmzz.biz and an MX record. all is pointing correctly. But still I can't connect.
Any ideas I what else I can check?
Thanks for all of your help.
