My email doesn´t works

[Santiago Carvajal]

My email does not receive or send emails, I have already tried modifying my dns, reverse dns, because I had read an article that this would solve it, but it did not have any positive effect, if you could help me I would be very grateful.

There can be many different causes of that delivery error. Generally, the "User unknown in virtual alias table" error means the recipient address does not exist in the destination server. This could mean that the MX records are misconfigured for the recipient domain, but there could also be other reasons. If you need further assistance, I suggest opening a ticket so we can look closer.
