Spamcop has blacklisted 220.127.116.11, which is a VM SMTP server hosted by Ziggo?
Here is the delivery failure notification:
SMTP error from remote mail server after RCPT TO:<firstname.lastname@example.org>: 550-"JunkMail rejected - smtpq5.tb.ukmail.iss.as9143.net [18.104.22.168]:59256 550 is in an RBL: Blocked - see https://www.spamcop.net/bl.shtml?22.214.171.124"
Please can you ask VM staff to investigate?

Thanks. I can confirm that 188.8.131.52 is no longer blacklisted, so this must have been a transient issue.
Spamcop entries normally time out after 24 hours unless there are further hits from the same IP address.
It still might be worth the Forum Team passing this on to security though.
