Try this:

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/gdbhelper /tmp/deliver.sh -d ${recipient}

And /tmp/deliver.sh contains:

#!/bin/sh

sleep 1
exec /usr/lib/dovecot/deliver $*

chmod +x /tmp/deliver.sh and deliver a mail. Hopefully you'll now
have /tmp/gdbhelper* file(s)? If so, copy&paste contents.
