I'd like to disable 'user' exim smtp logins (aka MUA logins) and repoint mail.my.domains to google (I'll just put in CNAME records)...but I don't want to interrupt our PHP scripts sending emails (thus I can't just kill exim). Specifically, where is the binding of exim to subdomains?
I'm guessing that I want to:
-change relaying criteria to local only (not sure the best way)
-edit my mail.* CNAME to point to google (my MX records already point there)
-edit my DNS zone templates to not automatically CNAME mail.*
Any help/tips/links to guides?
