Hello list,
Found rejects at ehlo/helo stage for seemingly sound hosts in the logs.
Here's an example:
-----------------------------------------------------------------
fkuipers@Achtung:~> sendmail -bh 194.109.127.139
**** SMTP testing session as if from host 194.109.127.139
**** but without any ident (RFC 1413) callback.
**** This is not for real!
>>> host in host_lookup? yes (matched "*")
>>> looking up host name for 194.109.127.139
>>> IP address lookup yielded smtpzilla3.xs4all.nl
>>> checking addresses for smtpzilla3.xs4all.nl

I'm confused. This is on a linux 2.0.39, libc5 intel box.
