Aha! Yep - that's what I used to do - but, if you look in the
READ_ME for this version of sendmail, under "Non-DNS based sites"
you find:
Non-DNS based sites
This version of sendmail always tries to connect to the Domain
Name System (DNS) to resolve names, regardless of the setting
of the `I' option. On most systems that are not running DNS,
this will fail quickly and sendmail will continue, but on some
systems it has a long timeout. If you have this problem, you
will have to recompile without NAMED_BIND. Some people have
claimed that they have successfully used "OI+USEVC" to force
sendmail to use a virtual circuit -- this will always time out
quickly, but also tells sendmail that a failed connection
should requeue the message (probably not what you intended).
A future release of sendmail will correct this problem.
and, after a quick perusal of the m4 files, you see that nodns
doesn't actually do anything anymore... and there is no
way to have sendmail not do DNS... in my situation, it always
failed talking to the name server, and then simply queued the
mail. (Exactly what is described in that paragraph....)
