Subject: [PATCH] inject: Anchor 'From mboxrd@z ...' search
Date: Tue, 19 Jan 2021 00:40:42 -0500
Message-ID: <20210119054042.11985-1-kyle@kyleam.com> (raw)

piem--write-mbox-to-maildir finds the bounds for each message by doing
a plain search for "From mboxrd@z", but of course nothing prevents
that from being within the text of the message.  Anchor it to the
start of the line to prevent false positives.
