cyrs imapd and reverse dns lookups

It seems that cyrus imapd always does a reverse dns lookup
for a connecting client (in service_main(), the calls to
getnameinfo() ) if I'm not mistaken.

Is there a way to disable those lookups? I couldn't find
one in the code, but I thought I'd ask before I code up
a patch ;-)

I'd like to disable reverse lookups because I sometimes connect
from IPs with broken reverse delegations, and those lookups
cause a long delay when connecting.

greetings, Florian Pflug
