not sending email
Posted: Thu Dec 04, 2014 2:53 pm
Hello,
this could be a million time asked question but I didn't find my answer yet.
I'm running a VPS on Digital Ocean with CentOS 6.5 x64
I use VestaCP, I have only one domain and one subdomain on server.
My problem is that I have created email addresses for my domain and I receive mails normal but I cannot send emails to everyone. Most of the mails I try to send I get a failure reply...
"Mail delivery failed: returning message to sender"
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:
info@*********.gr
SMTP error from remote mail server after MAIL FROM:<info@*********.gr> SIZE=2029:
host ************.gr [**.***.***.**]: 550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1)
Thank you in advance!!
