maybe i've missed some mail, but it seems to me you should
configure your sendmail for "SMTP after POP" operation. the
idea is that a user polling some POP box has to supply a
password, thus authentifies himself, so relaying for the users
IP address can be permitted for a specified time period, e.g.
so a roaming user just has to poll his POP account first, then
can relay mail from the current dialup IP address.
have a look at
the current eudora qpopper (which is standard for suse) already
includes the logging output needed, so the patch is not needed.
the popauth HACK for sendmail is still needed.
the popauther.pl sub add_new has to be extended for qpopper like
if(!$good && /^([A-Za-z]+\s+\d+\s\d+\:\d+\:\d+).*POP login by user
"([a-z0-9]+)" at \(.*\) (\d+\.\d+\.\d+\.\d+)$/)
# warn "add_new: qpopper...\n";
$tstamp = $1;
$user = $2;
$ip = $3;
i've configured all our mail servers this way, and it
works very well.
