Subject: [PATCH] filter/subjecttag: account for missing Subject: header
Date: Fri, 12 May 2017 18:49:32 +0000 [thread overview]
Message-ID: <20170512184932.20738-1-e@80x24.org> (raw)
This is a high indicator of spam (but out-of-scope for this
particular module) but sometimes it is not, and people
legitimately forget to set a Subject: header at all.
