Hi Brian, Thanks for explaining the testing procedure.

It is when I run ``check_mail mlt@111.org.'' that I get this status message. I think you are right that it is a DNS error because it takes a while to return this message (sendmail appears to timeout). So is there some configuration variable I need to set in sendmail.cf to correct this problem? Most of the spam domain names do not have DNS entries so they time out even with a ``whois'' command. I have the resolve part of the ruleset commented out just as shown in the example file so its not getting called from there. # Host must be resolvable, currently not used at hub.freebsd.org #R$* $| $* $: <?> <$1 $| $2> $>3 foo@$1 #R<?> <$*> $*<@$*.> $: $1 #R<?> <$*> $*<@$*> $#error $: 451 Domain does not resolve ($1) Do I need to uncomment the following in the sendmail.cf file?: # shall I avoid expanding CNAMEs (violates protocols)? #O DontExpandCnames > > Is this the stuff in: > > ftp://releng22.freebsd.org/pub/FreeBSD/releng22/XF8633/ > > Probably more like > > ftp://releng22.freebsd.org/pub/FreeBSD/releng22/src/etc/mail This is a bad link. There is no ``/src'' directory only the directory tree shown below. Here is all that's there: ftp://releng22.freebsd.org/pub/FreeBSD/releng22/ Current directory is /pub/FreeBSD/releng22 Up to higher level directory XF8633/ Sun Jun 22 00:00:00 1997 XF86331/ Thu Sep 11 08:49:00 1997 packages/ Sat Nov 29 11:48:00 1997 Maybe something has changed at the freebsd.org site.
