I recently set up a subdomain website, where the main domain lives on another server. They just set up the sub and pointed it to my ip address.
Everything works fine except for the e-mail sending of the forms on the site. The forms are configured to go to an email address of the main domain, and emails never arrive. I also have a cc set up to go to my gmail address. I get SOME emails but a few are missing.
Where should i look to troubleshoot? To solve the first problem, does my server think that it should be delivering email locally?
