Subject: base.m4: Accept bad synchronization from `submission' clients.
X-Git-Url: https://git.distorted.org.uk/~mdw/exim-config/commitdiff_plain/54341a709aa83dc80f23cc6a327e9c68dfd6e872

base.m4: Accept bad synchronization from `submission' clients.

Alas, Thunderbird is an offender, and this prevents it from using
`STARTTLS', which is a much worse outcome.
