This is something I had the pleasure of discussing with Dave
Sill some time ago:
As far as I know, qmail has 2 channels (as DJB seems to call
them) of messages: the local and the remote channels.
The formula for the time of a "next delivery" of a message
that has not yet been successfully delivered *after* the i-th
time it was tried is:
next_retry = birth + (i*c)^2,
where birth is the time when the message has first entered the
queue, c = 10 for local messages and c = 20 for remote
messages.
So, if you make a table of those values for c = 20 (that is
remote deliveries) and i = 0, ..., 39, you should get the
table Dave Sill has put on his site.
The relevant code is in qmail-send.c, function nextretry().

He is problem is probably related to trigger not being group
and world writable, me thinks...
