[Dovecot] Missing MIME-Version header in e-mails.

[Tan Shao Yi]

Hi,

I notice that in src/lib-mail/message-parser.c, there is a section of 
code that checks for the presence of MIME-Version before allowing 
processing of the Content-* headers.

Is there a possibility of relaxing this rule? There are some broken 
mailers, in particular newsletter mailers that do not seem to honour the 
MIME-Version header, though they do send the Content-Type.

Cheers.
