Ask HN: Zoho mail custom domain and alternatives

I was unable to find the answer on their FAQ, SO and forums (only vague information).

Basically I don't want any of my e-mails to be hosted by Zoho, just use it as POP/SMTP server that I call from Gmail. I have this setup working but with a few problems:

- After I send an e-mail a copy is stored on Zoho's SENT folder. I don't want that.

- All the e-mails I received are still appearing on the TRASH folder, they should just disappear. Or I might hit the quota if I don't manually erase the emails every now and then.

Yes, the option "Delete emails from the Server, when POP client issues a Delete command" is checked.

How do you manage? Is there a better option than Zoho? I can't afford $50 a year per user right now (it actually costs me about 3 times that after taxes since Google doesn't accept my local currency, same thing for the other options I found).

I'm worried about my e-mails getting on the spam folder and that's why I didn't considered Pawnmail.

I only need 2 or 3 e-mail accounts.
