The SMTP filter caught my eye. What are you doing, exactly?

I ask because we do Dial-up SMTP (ETRN, RFC 1985), and we also offer
Dial-on-Demand ISDN where we'll initiate a call and get CLID callback.

Both those things work fine, but not together. SMT bound for the client
will bring the link up. I toyed with call filtering SMTP so it wouldn't
bring the link up, but the trouble is that then it won't _keep_ the link up
either, so it could timeout in a mail transfer. Or...?

I'd like to prevent SMTP from going directly to an SMTP server on a dialup
link, but allow the client to get mail from my server using ETRN. Do you
have this working?
