Subject: Ignore "SANITIZED ... NULL byte(s)" messages.
X-Git-Tag: 1.51.04~11
X-Git-Url: https://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=6d985d29d8be2b70ee7e4048a7ae95e2b4013f17;p=amavis-logwatch.git

Ignore "SANITIZED ... NULL byte(s)" messages.

Newer versions of the amavisd daemon sanitize NULL bytes within the
body of a message for the benefit of Cyrus IMAP. When it does this,
the number of bytes sanitized is logged. This is an informational
message only as far as I can tell, so it's been added to the list of
messages to ignore.
