I found a possible cause. The DNS server which was listed first in my 
/etc/resolv.conf is down. I modified /etc/resolv.conf so that the first 
entry is the server itself and that seems to have really improved DNS 
performance (no surprise there). I'm trying to find out how long that 
server has been down to see if it correlates with the start of my problem.

Seems to me that having a dead box listed as the first nameserver in 
/etc/resolv.conf could easily hurt sendmail's performance. Do you guys 
think this is a likely explanation of my problem? I suppose time will 
tell but I'm interested in your opinions.
