Oh for crying out loud, a customer can receive emails but not send them. But it works when not connected to a VM system, ie a cellular connection or someone else’s WiFi!
Now there have been many, many reports on here of this and exactly what it means. Why it seems to be such a mystery to forum team members is a little odd as this has been going on for years!
Your IP address is listed on one of the Spamhaus blocklists and as such VM are actively and deliberately preventing you from sending email. You have some device on your home network which has become infected with some malware and is sending out spam messages. This has been picked up, reported to Spamhaus, your IP address has been listed and VM (for better or worse) have blocked you from sending emails.
Absolutely nothing you can do about it, other than find out the underlaying cause and fixing it. VM will not, indeed cannot help you with this, it’s down to you to do it. There are, I believe, some sticky messages at the top of this section regarding tracking down spambots on your network.
Again, why this seems to be such a mystery to the forum team members, I couldn’t properly say!
