Note: If you are getting spam coming from this domain, then you might want to look into SPF.  We are not afiliated with any spam operations.  SPF is a good tool that will block incoming dishonest spam attempts.  SPF is just a honesty check.  By enabling SPF on your server to verify connection information, you are able to tell other people that they can send email if they just be honest and tell us who they really are.  If they try to hide, then I don't want contact from them.

Note for spammers when it comes to SPF: If you just use your real personal contact information as who the message is coming from, then you are free to send email to me.  As previously stated SPF is a honesty check.  You use your real honest information and you can send.

It may be good to also install SRS if you do any type of forwarding.  SRS will rewrite the "envelope from" (not the from, the envelope from is the one in the Received header) so email forwarded through your server can get past the SPF checks.

Acronyms:
SPF - Sender Policy Framework
SRS - Sender rewriting Scheme

SPF version 1 is the better version.  SPF version 2 was an attempt of Microsoft to rework it to the "from:" and a "Resent-from:" header, but it breaks SRS too.  Most admin have gone back to using version 1 and having a bypass to accept all for version 2 because of the problems it introduced.  The idea of SPF is to block emails at the start of the communication (at the "mail from:"), not after the entire message was received.  (Checking headers or message body first wastes bandwidth.)
