Logcheck devel - Aug 2004 - Bug#263321: logcheck: Error and missing sendmail rules

Package: logcheck
Version: 1.2.24
Severity: minor

There is a regexp error in ignore.d.server/sendmail:

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ (sendmail|sm-mta*|sm-msp*)\[[0-9]+\]:
[:alnu\m:]+: [:alnum:]+: DSN: Return receipt$

It should be 

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ (sendmail|sm-mta*|sm-msp*)\[[0-9]+\]:
[[:alnu\m:]]+: [[:alnum:]]+: DSN: Return receipt$

([:alnum:] should be in character class according to POSIX)

There are also some missing ignore rules for 
sendmail+milter+spamassassin.

Milter change or Milter message is not identified

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ (sendmail|sm-mta*|sm-msp*)\[[0-9]+\]:
[[:aln\um:]]+: Milter (change|message):.*$

Sendmail seems to use now queue-id[linecount] if log message is multiline

Aug  3 18:25:51 palvelin sm-mta[2935]: i73IPO01002935[1]: Milter add

Following eats all following lines (as there is no easy rule to match 
for rest of line, as it may start from any point).

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ (sendmail|sm-mta*|sm-msp*)\[[0-9]+\]:
[[:aln\um:]]+\[[0-9]+\]:.*$

Also spamassassin X-Spam-Report header triggers security event as many 
rules have something that is "invalid" (or INVALID) 
(violations.d/logcheck).  A fix would be adding Milter messages

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ (sendmail|sm-mta*|sm-msp*)\[[0-9]+\]:
[[:aln\um:]]+: Milter (change|message):.*$

to violations.ignore.d/sendmail.
