OK, here's the deal. For the past several months our company has
been
receiving a LOT of delayed emails. Some by a few hours some by a few
days. As you can guess, this is a serious problem. I've tried
several things to resolve this situation:
<snip>
A Records
Host Points To
@ WWW.XXX.YYY.36 (web server)
mail WWW.XXX.YYY.37 (exchange server)
exchange WWW.XXX.YYY.37 (exchange server)
CNAMES (Aliases)
Host Points To
www @
MX (Mail Exchange)
Priority Host Goes To
0 @ mail (A Record for exchange server)
________________________________________________________________________
GoDaddy.com says that "@" simply refers to the domain name in
question. So, I thought "maybe it would be OK to have the A record
for @ pointing to the web server (WWW.XXX.YYY.36) and then a MX record
for "@" pointing to the exchange server (WWW.XXX.YYY.37)
It would appear that line of thinking was incorrect. When I set up my
test domain as above, I could not receive emails to that test domain.
I would like to see the actual domain name, but it should actually look
something like this. Without seeing the actual records it is only a wild
guess.
@ 900 IN A <IPAddress>
www 900 IN CNAME domain.com
mail 900 IN A <IPAddress>
@ 900 IN MX 10 mail.domain.com.
<Please note- regardless of the E-Mail domain, the MX record should point
to the A record that matches the SMTP HELO name.>
