[nos-bbs] new smtp gateway options

[Maiko Langelaar]

Hi Bob,

> I assume it still checks the rewrite file

I haven't changed any of that. The last thing in the whole
process is connecting to an SMTP server to deliver the final
message. All I've done is switch the SMTP destination. The
rewrite and stuff is done *long* before that.

Hope that makes sense.
