First of all I want to say gravity forms is the greatest WordPress plugin I've ever used and you guys have done a great job with this!
I am having a problem though, which is more than likely related to my server but I figured someone might have some idea how I can fix it.
I have a dedicated server from Host Gator and the PHP mail() function is enabled by default and the email notifications will work on a domain that I haven't made any changes to the MX records on.
However.. I change my MX records in my DNS (on most of my domains) so I can use Google Accounts to control the my email address, calender, etc. This is just something I've gotten use to doing on all my domains and like the imap email Google offers for free.
Anyways I'm assuming this is my problem, have you guys ran into this scenario in the past? I noticed in a previous support ticket you recommended an SMTP plugin however I'd rather not install this plugin on every one of my websites if there's an easier solution. Also with hat being said it might be a good feature to include in future releases of Gravity Forms so users can choose how emails are to be sent.
The strange part is the emails that WordPress generates when theres a new comment on a post are sent and received without a problem, I'm wondering if they are using a different method to send mail via PHP?
Hope that was clear and I'll look forward to hearing back from someone, Thanks!
