Legitmate emails to plusnet blocked due to spam causing issues to buisness

[#1]

Hi,

Emails being sent to plusnet email addresses our company are being blocked as spam with the following message:

Failed [host mx.avasin.plus.net[212.159.8.200] said: 552 Spam Message Rejected (in reply to end of DATA command)]                      

This has happened since the 16th June, this is a legitimate business address and is affecting business emails being sent to customers.

Does anyone know how to contact the postmaster to resolve this

If you can direct message me with the IP address(es) of your mail server and an example of one of the emails that's being rejected then I should be able to get the issue sorted for you.

Our golf club use Intelligent Golf to run the club.  It would appear that we are suffering the same problem with emails to and from the system using a Plusnet address are being blocked.  Can it be fixed?

This could be an issue with YOUR email service (MTA).

It would be wise to check out your domain against a black list checker such as - http://mxtoolbox.com/blacklists.aspx - this site has a lot of tools to help you discover the health of your own domain - for example, does it has an SPF1 record which inhibits your domain's email addresses from being spoofed?

Here is a report of my domain hosted by PlusNet... there's room for some improvement here!

There are measures being put in place by many of the ISPs but sometimes this can fall foul of originating email services not being proactive in helping to mitigate propagation of SPAM - for example Virgin ran into issues when it sought to protect its user base from the increasing risk of SPAM - see the 5th post here - http://community.virginmedia.com/t5/Email/Opt-out-of-of-SPF-authentication/td-p/2993853

We are getting responses like below when sending to your domains emails

Hi Simon,

A warm welcome tot he forums.  If Plusnet's spam filtering service has reasons to be concerned about inbound emails, they will be rejected.  It would help if you could post the response email headers here (redacting personal stuff) so that a staff member can look more closely at the issue.

What happens if you send an "empty" test email containing no URLs etc.?

Simon's been in touch over PM and the issue is now resolved.

An email to a regularly used valid plusnet address returns an error:

  The mail system

mail@xxxxxx.plus.com: host mx.avasin.plus.net[212.159.8.200] said: 552
    Spam Message Rejected  (in reply to end of DATA command)

Yet when it is subsequently forwarded to the very same address goes though ok. Can anyone help?

Can you private message me with the email content you're sending please, I'd need to see any URLs that are included too.

Please send me a private message
