I've been using it for over a year and the only problem any of my
customers have had was when they didn't understand they had to check
mail first. Noone's ever complained about losing outgoing mail because
of it. The SMTP transaction should fail before it completes so the
mail should remain in the user's queue. I chose this version over the
other one(s) BECAUSE I didn't have to patch qmail.

Nope, they're renewed for a configurable time period (I have it set for
10 minutes) each time they check mail. As long as they're sending from
the IP that checked mail RELAYCLIENT is set.
