Actually, they will, at least in some cases, keep trying indefinitely.
All FDT's systems went anti-relay many months ago...yet:

Aug  2 00:00:23 irc sendmail[18812]: Ruleset check_rcpt
(< at>) rejection: 571 
< at>... we do not relay - if you believe
this to be an error, contact support at

Someone told me that a spam package was distributed that specifically
targets IRC servers as relays.  It would seem they don't bother updating
the list, or their software is so popular that old versions stay in use.

The system above blocks about 3,000 relay attempts per day, every day,
since it got the anti-relay patches months ago.
