E-mail being rejected - 554 5.2.0 Spam content found
We have been sending e-mail for weeks to our various end users without, and recently have started encountering problems sending e-mails to @ ntlworld.com and @ blueyonder.com e-mail addresses. The failure message is as below:
This message was created automatically by the SMTP relay on mail.************.com.
A message that you sent could not be delivered to all of its recipients.
The following address(es) failed:
SMTP error from remote mail server after end of data:
host mx.mnd.ukmail.iss.as9143.net [220.127.116.11]:
554 5.2.0 Y8mq1t00o58SkYL018mrUT Spam content found
Is there anything you can do/we can do to avoid this happening please? We are not seeing this problem on any other e-mail provider and we don't appear to be blacklisted anywhere. SPF records all appear in order, etc.
Thank you in advance.

I am sorry we were a bit slow responding and you were having problems emailing our domains. We are presently taking steps to deliver suspected spam email to our customers, allow them to decide on its legitimacy and then update our filters, more information here Spam Folder Settings Change
It may take us a few weeks to fully implement but once done fingers crossed it will sort your problem, if not do let us know and we will be happy to investigate further.
