ok, I have one server that is a standalone webserver. it's mint7 and is for design projects and my blog, etc. it's FQDN is "tranquilpenguin.com" I have another server that is for production sites, and it also hosts email for "@tranquilpenguin.com" I have the mx record set up correctly. Question: If I cannot email via sendmail (php mail form) to @tranquilpenguin.com from the first server. How to I make the server understand that it doesn't host email for that domain and force it to use the mx address instead? Thanks.
