[Patch] handle "improper command pipelining" message correctly none

Description Robert Scheck 2013-01-10 23:31:47 UTC 
Description of problem:
Logwatch does not handle "improper command pipelining after (NOOP|RSET)" as
it is shipped right now with RHEL 6. Reproducing is easily possible, simply
add "reject_unauth_pipelining" to "smtpd_recipient_restrictions" in main.cf
and get a dumb spammer who didn't learn to behave according to SMTP RFCs.

Version-Release number of selected component (if applicable):
logwatch-7.3.6-49.el6.noarch

How reproducible:
Everytime, see above and below.
  
Actual results:
Logwatch does not handle "improper command pipelining after (NOOP|RSET)"

Expected results:
Logwatch should handle "improper command pipelining after (NOOP|RSET)"

Additional info:
According to logwatch upstream there seems to be a patch for this already:

Comment 2 Robert Scheck 2013-01-11 00:00:46 UTC 
Actually, we see NOOP/RSET/HELO in the wild currently, the patch covers them
all - which is likely the best.

Comment 4 Jan Synacek 2013-01-14 14:25:07 UTC 
Testing package:

Comment 5 Robert Scheck 2013-01-18 10:05:42 UTC 
Applying this package removes the patch from bug #799987 - which unfortunately
still did not make it into any stable release yet.
Comment 6 Robert Scheck 2013-01-18 12:15:20 UTC 
The testing RPM fixes the initially described issue for me, however comment #5
applies for that testing package.
