Re: Help! Smtp authentication?

[Thomas Mueller]

I just looked through RFC 2554, which deals with authenticated SMTP, seems to
raise more questions than it answers.  This dates to March 1999.  I didn't find
anything more recent on authenticated SMTP, but possibly there might be since my
last download of the RFC list.  I think there is http://rfc.net, or check
http://www.cis.ohio-state.edu/hypertext/information/rfc.html

I think there might be some open-source email clients that support authenticated
SMTP.  I'd check the Perl Mail (SMTP & POP3) modules, GNUS which runs under
Emacs, Pine, sendmail, qmail, and other Unix email clients.  I don't know what
WATT-32 has but intend to look through that anyway.

Problem with allowing outside access to an SMTP server, even for local access 
only, is that users of that service could be bombarded with spam from outside 
users.
