Unless I missed it in the thread some where, you haven't said what 
domain you're actually checking up on, so it's hard to know if the above 
output is correct.  Hypothetically, if your MX record points to 
mail.example.com but you connect to that server and it says it's 
spunkymail-a5.dreamhost.com, you should change your MX record so that it 
says your pointing to spunkymail-a5.dreamhost.com.  That's roughly what 
the original message was complaining about, if my understanding is 
correct.  As the message said though, it's just a warning, and isn't at 
all uncommon to have an MX record pointing to the A record 
"mail.example.com", which is in fact something like 
captnkirk.example.com, and responds as such in its connection greeting.  
Whether you can control it or not, wether you choose to change your MX 
or not, this one isn't worth loosing any sleep over.
