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
