I went through few topics but didn't successfully catch an answer. The thing is, I can send emails from both test page in backend and roundcube mail ui but can't receive any mail to server. I've tried to send from gmail but there is no mail delivery. If there is need for logs I will post it, tell me which one you will need. Also all mail ports are open so it's not port issue.
MX Record, A Record, SPF Record, DKIM & DMARC is all checked green OK and SSL is setup.
Thanks in advance for assistance
