[Logcheck-devel] Bug#625895: logcheck-database: /etc/logcheck/ignore.d.server/dovecot rule misses unusual Message-Id

[Gerald Turner]

Subject: logcheck-database: /etc/logcheck/ignore.d.server/spamd rule misses unusual Message-Id
Package: logcheck-database
Version: 1.3.13
Severity: minor

*** Please type your report below this line ***
Hello, I've seen some legitimate mails with unusual Message-Id headers
that cause logchecks dovecot delivery rule to be bypassed.

Example: … sieve: msgid=<20110422T2108.GA.(stdi.stse at fsing.rootsland.net>: stored mail into mailbox 'Mailing Lists/Debian/debian-devel'

Note the open paren in the Message-Id.

Rule is:

^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ (dovecot: )?deliver\([-_.@[:alnum:]]+\): sieve: msgid=<?[^\(]*>?( \(((added by )?[^[:space:]]+|sfid-[_[:xdigit:]]+)\)?)?[[:space:]]*: (stored mail into mailbox '.*'|marked message to be discarded if not explicitly delivered \(discard action\)|(forwarded to|sent vacation response to|discarding vacation response for message implicitly delivered to|not sending vacation response to system address|discarding vacation response to mailinglist recipient|discarded vacation reply to|discarding vacation response to (auto-submitted|precedence=bulk) message from|discarded duplicate (vacation response|forward) to) <[^[:space:]]*>)$

Proposed fix (assumes Message-Id can't have spaces):

^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ (dovecot: )?deliver\([-_.@[:alnum:]]+\): sieve: msgid=<?[^[:space:]]*>?( \(((added by )?[^[:space:]]+|sfid-[_[:xdigit:]]+)\)?)?[[:space:]]*: (stored mail into mailbox '.*'|marked message to be discarded if not explicitly delivered \(discard action\)|(forwarded to|sent vacation response to|discarding vacation response for message implicitly delivered to|not sending vacation response to system address|discarding vacation response to mailinglist recipient|discarded vacation reply to|discarding vacation response to (auto-submitted|precedence=bulk) message from|discarded duplicate (vacation response|forward) to) <[^[:space:]]*>)$

Thanks!
