Whenever we send an email (not bulk or spam just a simple message to a single address) to a virgin media / ntlworld account is is returned with the a message like the following error:
xxxx rejected your message to the following email addresses:
email@example.com (firstname.lastname@example.org)There's a problem with the recipient's mailbox. Please try resending the message. If the problem continues, please contact your email admin.
xxxxx gave this error: WCt41t00E289cog01Ct5Tx Spam content found
Our email is with Office 365. Our domain is with GoDaddy. This problem only affects virgin media type addresses - other mail is successfully delivered. The recipient continues to receive other email (i.e. the email address is valid and active). The emails are not going to their spam folder but rather not being delivered at all. The content of the email can be anything at all - even just a simple 'Test' or blank message, everything seems to fail.
I'm sorry to see that it has been a week and you've had no response to your report that PACE Theatre Company is unable to deliver emails to addresses at Virgin Media domains (@blueyonder.co.uk, @ntlworld.com, @virginmedia.com, and @virgin.net). Can you confirm that the theatre is able to deliver similar messages without any issues to large email providers such as Gmail, AOL, Yahoo! or Hotmail?
When you do receive a response from Virgin Media, would you please report here how the problem was resolved to help other businesses which will be reporting the same problem in the coming weeks, given the ongoing nature of this issue since August 2015?
