Re: Cant send and receive mails
Your log doesn't say that it's DNS problem, someone is trying to access your mailbox by using brute-forcing, which is quite obvious.
It would be better to transfer this question to Mail section.
But frankly speaking about DNS, have you created MX records on your VPS? also are you using PTR? If yes, then it's not DNS problem at all. Check configs, dovecot, regex and exim conf.
