Subject: Fix buffer update for DKIM.
X-Git-Tag: 0.7.5~4
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=6cb614e6194de39fafd4eb05ad69a1b4aeef17f1;p=rspamd.git

Fix buffer update for DKIM.

Sometimes this procedure was able to split \r\n in messages which in
turn led to DKIM checks failures.
