This depends on how long the mail is already in the queue.
qmail uses an quadratic backoff algorithm. The timings are available
at (the URLs are from this list as of yesterday):
http://www.lamer.de/maex/creative/software/qmail/times.html
http://Web.InfoAve.Net/~dsill/lwq.html#retry-schedule
We do deliver emails for this kind of domains to a "serialmail channel"
via virtualdomains and qmail/users mechanism and then a script is run
every n minutes and tries to deliver this emails via maildirserial.
Thus the customers have to stay online for at least n minutes till
the transfer is initiated + the time it takes to deliver the emails.
Someone posted on this list some time ago they are working on a solution
that will trigger maildirserial via the radius server, however they were
not finished the last time I asked. You should be able to locate the
message in the archives.
Another approach which should be rather easy to implement as you are using
static IP adresses is to have a script (e.g. cgi-bin) that the customer
calls and that triggers the delivery.
