I've recently had a problem I haven't seen before (using vpopmail
4.9.6-1):
I got a number of clients who couldn't log into their server all of a
sudden and the logs were showing an error about an unrecognised response
involving "tcprules: fatal: unable to parse this line:
::ffff:172.16.10.1:allow,RELAYCLIENT="""
I recognised that vpopmail was obviously adding an invalid entry to the
relay table, so I checked my MySQL table and sure enough, there was an
entry to allow relaying from "::ffff:172.16.10.1". I removed the entry,
and that fixed it. That machine is the local server, btw.
Looking at vmysql.c (or the equivalent for non MySQL entries), shouldn't
vopen_smtp_relay(), around line 570, have a check to see if the IP
address is valid?
I compiled with: ./configure --enable-roaming-users=y --enable-logging=y
--enable-mysql=y
