DNS maps hostnames to IP addresses, like this:

    $ host tlug.ss.org
    tlug.ss.org             A       204.225.177.38

It can also do the reverse, mapping IP addresses to hostnames:

    $ host 204.225.177.38
    Name: tlug.ss.org
    Address: 204.225.177.38

The mail server in question is probably rejecting your email because your IP 
address does not have a reverse mapping (PTR record).  It is not standard 
practice from what I see to block based on a missing PTR but it is not that 
uncommon either ... you should fix it.  Contact your ISP and advise them that 
you would like reverse entries installed for your IP addresses (the IP 
addresses that you use when connecting to the Internet).
