First: Thanks to Apachefriends for creating such an excellent product bundle...and thanks for providing an english area in this forum too!
I have a few questions about the Mercury Mail setup...(I have read just about all of the threads on the topic...still have questions)
6 domains resolving to my IP
Port 25 is open on my router/firewall hub, I am unsure if my ISP blocks or filters it, but I believe it is open (how can I test?)
Entries in system32/drivers/etc/Hosts that resolve all names to my IP (including the "mail.mydomain.com" ones)
A, CNAME, and MX records on each example below:
mydomain.com MX 0 mail.mydomain.com
mydomain.com A 24.xxx.xxx.xxx (blanked out for my protection)
mail.mydomain.com A 24.xxx.xxx.xxx (blanked out for my protection)
www.mydomain.com CNAME mydomain.com
All domains resolve correctly on HTTP, so the DNS management is operating well.
I used mail.mydomain.com as my "internet name for this system"
I have my 2 ISP Name servers entered in the MercuryE "Name Servers"
I entered "mydomain.com" into the local domains on the core configuration (should this be mail.mydomain.com?...or should mydomain.com be in my hosts file?)
I sent a mail from Mercury's file->send mail message and it works.
I sent a mail to an outside address, and it worked.
I sent a mail form an outside address to email@example.com, and it did not work.
I am sure I am missing something, but I can't seem to find out what it is...
Any help is greatly appreciated (then I can try to figure out how to get the other 5 domains accepting mail on the same server instance!)
