dovecot - Jan 2007 - Vpopmail auth with vchkpw

Hey Guys,

I'm using vpopmail, and was told here that I need to use the vchkpw
passwd module to authenticate AND get my lastauth data updated.

It works like a charm, but I've come across another minor issue.

vchkpw sets the 'connection-type' based on the variable TCPLOCALPORT
If that's not set, it defaults to pop.  What this does in my environment
is cause someone who is denied POP access to also not be able to use
IMAP (or webmail) because that variable is not set.

Is it possible to have Dovecot set that variable, based on the port the
user connected to, prior to calling vchkpw?

Or can I Set that in here somehow?

passdb checkpassword {
        args = /usr/local/vpopmail/bin/vchkpw
    }
    userdb prefetch {
    }

}

Thanks

Rick

Unfortunately Dovecot doesn't currently pass the port information to
dovecot-auth, and I think it's a bit too large change to do for v1.0
release. Dovecot does set SERVICE=imap or SERVICE=pop3 though, so it
would be possible for you to write a glue script as the checkpassword:

#!/bin/sh

if [ $SERVICE = imap ]; then
  export TCPLOCALPORT=143
else
  export TCPLOCALPORT=110
fi
exec /usr/local/vpopmail/bin/vchkpw
