I can send, but i cant receive email

[mikasa]

Solved

i try disabling DNS proxy from CF, and now email from gmail received

i follow tutorial from this guy:

The e-mail does not reach my inbox

I have already found the solution. There was a problem with cloudflare. subdomains like mail.domain.com webmail.domain.com pop.domain.com smtp.domain.com DNS cannot be proxided. I leave it here, maybe someday this information will be useful to someone.
