Betreff: Re: [exim] lowest numbered MX record points to local host
So what shoud I do to fix that? I can't use local_domains, becouse it's
shared hosting, and users can add domains by hand.
If someone will add domain 'gmail.com' exim will treat it as local domain.

The only way is to check MX.

Bambero
