Package: ssmtp
Version: 2.61-12
Tags: patch
Severity: wishlist
Hi. Included below is a patch to configure logging in ssmtp.
It adds the option of setting 'log_level' via the config file.
This patch also makes a minor change in the way logging behaves:
- Setting "loglevel=1" in ssmtp.conf will cause the SMTP dialog to be
syslogged but the message contents (from "DATA" to the final ".")
will not be syslogged. This setting can be used to keep track of
SMTP sessions.
- Setting "loglevel=2" in ssmtp.conf will cause both the SMTP dialog
and the message contents to be syslogged. This setting can be used
for full debugging.
Hope this helps.
