As this site already mentions you should store the mails somewhere and
use a smtp-client to push the messages to the destination hosts as soon
as it authenticates via some arbitrary means...
I just wanted to add another SMTP-client I used some time ago,
from the qmail-author D. J. Bernstein:

You probably will have to add some wrappers for exim being used, instead
of qmail...
If I remember correctly some time ago UUNET had a simmilar process
set up here in germany (don't know where else). As soon as your dial-up
connection was established, they would connect to your local port 25 and
send you the queued emails. You could do this, too, if your users are
authenticated on dial-up time via a local radius-server for example.
