I've found that not to be the case. A 30 second delay will ONLY be DNS the 
first time. The DNS server near (or co-resident) with the server providing 
caching will cache either the positive or negative result. So, you might 
see a 30 second delay once, but if you then check your mail a second time 
and get another 30 second delay, that would point elsewhere.

I've found the 30 second delay to be a telltale sign of IDENT processing in 
XINETD. Indeed, in Xinetd, someone hard-coded 30 seconds as a timeout, and 
didn't even provide a way to alter that value. Removing USERID logging in 
your xinetd config will turn this off, give or take bugs in xinetd that 
seem to turn it back on.
