Appreciate if someone could let me know what is happening here please.
Sent an email to a contact of mine and received back the following error (I've ***'ed the email address for privacy reasons). Quote:
The MX record for s****.com is mx1.spamwall.co.uk. It looks like fastmailusercontent.com is being blacklisted. Am I correct? How can I resolve this? Or is it down to Fastmail? cheers E |
The message should mean that fastmailusercontent.com is on the Spamhaus DBL (domain blocklist). However, I just did a check at https://www.spamhaus.org/lookup/ and that domain is not on the DBL. I suggest retrying the sending of your message. I suspect it was a short term issue (possibly even an error by Spamhaus). If the message is still failing, open a support ticket.

I subsequently sent the email and redacted all references to fastmailusercontent.com (arose due to an attachment from a previous email in the same thread) and message went through just fine. I assume Fastmail have a process of catching when their domains and/or IP address ranges get on spamlists and take appropriate actions. So I won't bother annoying them with a ticket. Luckily the MX server sent me a fail message so I could take action. One has to wonder how many MX servers don't bother and simply discard messages based on blacklists. |
