Sendmail and smtp-auth

[Gary Lowder <malloc@mudbug.org>]

Ok, I've been beating my head against a wall for a while, and the wall 
needs some relief.

How do enable smtp-auth when using Sendmail?  Testing's Sendmail 
(8.12.6-7) says it supports SMTP AUTH (SASL/PAM).  I've also installed 
the libsasl-modules-plain, and libsasl-digestmd5-plain.  Reading SASL's 
docs talks about having an entry for type of password in Sendmail.conf, 
"pwcheck_method:" (sasl's Sendmail.conf, not sendmail's sendmail.conf), 
but the docs refer to it being placed in /usr/lib/sasl/.  With Debian's 
file layout, those are not config files, but the libs sasl uses.  I'm lost.

Thanks for your time and effort,

Gary.
