Email Options

[Nosey]

I have been trying to figure out what my email options are, and what I have found I'm not happy with

I have my own domain name and custom email address and use a gmail account.

via the web/gmail I can send email using my custom email address as the return, but I don't get notified of emails

via the touch email I can send email using my custome email address, but for some reason it doesn't update and notify new emails correctly, I have set it for a min of checking every 5 minutes up to every 30 minutes and more then none I have to manually check for email

via seven it checks correctly with any time I set, but it won't use my custom address, it only uses my gmail.com address, which I would rather not use..

any suggestions, ideas, etc..

thanks in advance
