+ It's probably something wierd in your TCP implementation that
+ makes the IDENT code act oddly. On most systems V8 tries to
+ do a ``callback'' to the connecting host to get a validated
+ user name (see RFC 1413 for details). If the connecting
+ host does not support such a service it will normally fail
+ quickly with "Connection refused", but certain kinds of
+ packet filters and certain TCP implementations just time out.
+
+ To test this, set the IDENT timeout to zero using
+ ``OrIdent=0'' in the configuration file. This will
+ completely disable all use of the IDENT protocol.
+
+ Another possible problem is that you have your name server
+ and/or resolver configured improperly. Make sure that
+ all "nameserver" entries in /etc/resolv.conf point to functional
+ servers. If you are running your own server make certain that
+ all the servers listed in your root cache (usually called
+ something like "/var/namedb/root.cache"; see your
+ /etc/named.boot file to get your value) are up to date.
+ Either of these can cause long delays.

+
+ You need OSTYPE(systype) in your .mc file -- otherwise the
+ configurations use a default that probably disagrees with
+ your local mail system. See cf/README for details.
