Folks, I am fairly clueless regarding some things....can someone
please explain?

I have an Exchange Server, and a Barracuda spam blocker. If I do a
www.ipchicken.comto check my ip it comes out to:

mail.mycompany.com. As far as I know email comes to the Barracuda
which then sends it to the Exchange server. So I have
barracuda.mycompany.com. If I look at my DNS, and MX records I see the
following:

Host                                                    Numeric IP
www                                                   12.xxx.xxx.xxx

@ (None)                                           12.xxx.xxx.xxx

* (All Others)                                      12.xxx.xxx.xxx

mail .mycompany.com                          199.72.xxx.xxx

pop .mycompany.com                          199.72.xxx.xxx

My barracuda's ip address is a 12.XXX.XXX.XXX. We have been getting
mostly spam lately. The hosting company changes our MX records a few
times which caused email to stop. I'm thinking that one of the
addresses, either the pop or mail should point to the
barracuda.mycompany.com. But I don't understand this stuff well
enough. Could someone explain?

Where oe what is your MX record?
Without an MX record at the root of your domain, e-mail will be attempted to
be delivered to the A record at the root of your domain.

Having an A record for mail.mycompany.com does not mean mail will be
delivered to that name's IP. But an SMTP server will first look for an "@"
MX record, if one is not present, it will look for an "@" A record, which
you have. As for whether it is the correct IP, that's another question but
an SMTP server that is compliant with RFCs will attempt mail delivery there
in the absense of an MX.

So if I understand this correctly, since there is an MX record it will
send the mail to what's in there, right? The frustrating part is that
I don't know if the MX is correct. According to the hosting company
NOTHING has changed even though I have had to correct it 3 times
already just to get mail to come in.
