Re: DNS, MX , CNAME,.....HELP!

I've just checked using your domain's authoritative NS(ns31.worldnic.com). You have 2 MX records.

According to both servers' answers, I think 199.72.199.77 must be your barracuda server. (It answers "250 barracuda.heartworld.com")

The reason you received spams recently is you have mistakenly set another MX record.

The Email sending process works like this:

The server receives mail -> The server checks the host name after '@' of receiver's address -> The server requests MX record of the
host name
->
a)if able, connect the host specified by the MX record.
b)if there are many, connect first one, if failed, the next, then on.
c)if no MX record, try A record, that is the IP address of the hostname itself.

Since you have 2 MX, then some mailservers connect 199.72.199.77, and some else connect 199.72.199.78 randomly. 199.72.199.78 is not
filtered, so spams goes inside.

Yesterday I suggested you test your barracuda, and you said none was received. I found that barracuda.heartworld.com, or
12.130.50.16, is not your real barracuda, nor your mail server (but it is your www server, according to the www's A record.), so
after a few hours or days you'll receive error message stating that barracuda.heartworld.com or 12.130.50.16 cannot be connected.

To make everything correct, I suggest you make 2 changes as follows:
1) Delete this: heartworld.com, MX, 20, pop.heartworld.com
2) Modify barracuda.heartworld.com's A record to 199.72.199.77

I hope it would not be very difficult to understand my poor English, as Eng is not my native language.
