Except for IMAP before SMTP (roaming users).

No one has responded to these posts, so either I'm the only one using this
feature with these versions, or the only one that is having the problem.
I'd love to know if someone else has it working successfully with
4.10.35/1.3.10.
Cheers,

Bill, I took a crack at your roaming users problem last night and I came
up with a solution that I'm happy with.
The basic problem is that the newer version of courierIMAP has seperated
the authentication process from the couriertcp process by using
authdaemond. So when vpopmail's open_smtp_relay function get's called it's
unable to retreive the remote user's IP address from the environment
variables. To fix this I've written a program that can be dropped in
between imaplogin and imapd. This program will only be called if the user
has been authenticated. It will call open_smtp_relay with the proper
environment variables set, then it will call whatever program is passed
into it's argv[1] parameter.
Run sh ./build to build open_relay, if the compile fails with complaints
about crypt add -lcrypt to your ~vpopmail/etc/lib_deps. Install open_relay
whereever you like, I put mine in /usr/local/bin. Modify imapd.rc, or use
the one I attached. The important line is this one:
$PORT ${exec_prefix}/sbin/imaplogin $LIBAUTHMODULES \
${exec_prefix}/bin/open_relay \ #This will setup open_relay for roaming users
${exec_prefix}/bin/imapd Maildir"
Don't forget to put ~vpopmail/bin/clearopensmtp into your cron!
Enjoy,
Chris
