I cannot sent an email
I try to send an email, but I received this message every time:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
[email protected]
host smtp3.xxx.com [201.249.229.211]
SMTP error from remote mail server after initial connection:
550 Rejected due to DNSBL server response. (dnsbl.cobion.com - 144.208.79.24)
I deleted the email account and the name of the host.
Please, What can I do?
Many thanks in advance
