Re: [vchkpw] IP Domains and Courier IMAP
Hi Bill, Original response below, but one question... Why does it work when using tcpserver (but I'll still take a look a preauthvchkpw.c) ie tcpserver -R -t 2 -g 89 -u 89 0 110 /usr/lib/courier-imap/sbin/pop3login \ /usr/lib/courier-imap/libexec/authlib/authvchkpw /usr/lib/courier-imap/bin/pop3d Maildir Thanks for the response. It feels so good when I stop banging my head. Not much of a C programmer anymore, but I'll whip out my old books and see what I can do in the next couple of hours. Thanks again for the response, that helps greatly.

(note to self: check answer BEFORE hitting send). I'm going to run some tests, but my hunch is that it may be related to getting the IP from couriertcpd. I'll post my findings shortlly.

If so, try again without it (--without-authdaemon). I'm rebuilding
courier-imap to run some tests, and see if there's a problem with the
IP formatting (IPV6) of TCPLOCALIP that couriertcpd sets (as suggested
offlist by Vladimir Kabanov).
Ok, Vladimir was right, TCPLOCALIP is in IPv6 from couriertcpd. So, I
just converted it in host_in_locals(), and now authvchkpw works.
However, authdaemon still will NOT work, since TCPLOCALIP does not get
passed to authvchkpw. The patch below applies to 5.3.11 (available at
http://shupp.org only right now), but you may be able to apply it to
your version with little effort. Let me know if this works for you.

Re: [vchkpw] IP Domains and Courier IMAP
Hi Bill,
I'm running 5.3.8 and I am running without authdaemon
(ie --without-authdaemon). I'll try the patch later on tonight or first
thing in the morning (I have little one's to put to bed now).
Thanks for the help.

Rick
