My pleasure.

Note that you would need to have some kind of fall-back and retry code
for the times that the GUI is not running. You may be able to integrate
that into the sendmail infrastructure, by returning a "temporary
failure" result to the calling sendmail process, and letting it worry
about rescheduling the message for transmission.
