Hello,
when send from sentora to Gmail or Outlook, my email go to spam. My IP is 82.117.221.14 and it is blacklisted. When I requested to remove from black list they say me
"You ONLY need to remove the IP Address from our list if you are running an
outgoing mail server.
(If you do NOT run an email server on this IP address, then being on this list
should not affect you or your ability to send email through your email provider.
If it does, please contact your ISP or email provider to correct. It can be a
problem with the email server, or your email client may not be configured
correctly.)
If you ARE running an email server, your PTR (reverse) DNS is the problem.
This does not conform to 'Best Practices' recommendations for Network Operators,
and Email administration and as such is much more likely to be an access point
from which Trojans and Bots are being used to send Spam.
You should first, of course, ensure that the problem that got your IP detected in
the first place (i.e. infected PC's or a spam leakage) gets rectified. However, once
this is done you should contact your upstream provider or change the PTR
(reverse) DNS yourselves to something more suitable.
According to 'Best Practices' guidelines (and I can give you several references
if you like) the hostname of an IP Address used to send email should resolve to
the responsible party's domain. In this case, the host name resolves to your
upstream provider, who aren't responsible for the mail server at that location.
Simply changing the reverse DNS to something like..
eg..
mail.your_domain.com
-- or --
gateway.your_domain.com
Once this is done, it would allow the IP Address to be removed, and also prevent
the spread of Spam from trojans and bots. You may need to wait for the DNS
change to propagate before removal."
