Good luck; you'll need it. It sucks, but even though I am *highly*
reluctant about doing it, I finally had to start blocking dialups/ADSL.
*Far* too many zombie Windows users. Even with stringent SMTP-time
checks, still too many CPU cycles wasting scanning endless streams of
viruses, fraud and spam, and too many end users ultimately getting spam.

This has been requested before, but would be in serious breach of RFCs.
If a mail is permanently rejected, it's permanently rejected. This
means you shouldn't retry it automatically. So there isn't an easy way
to do this, although that's not to say you couldn't invent some
tortuous submission system that processed the rejection from Exim and
automatically resubmitted. However, I'd save yourself the hassle,
complication and uphill battle and just get an off- site SMTP smarthost
instead, if your ISP's mail servers are unreliable. And/or moan at your
ISP about not providing you with a decent smarthost.
