I am a member of a club that uses Groups.io to communicate. It has a facility for forwarding a message posted on a group to all the members in the group. I have intermittently not been receiving messages forwarded by Groups.io because they have been bounced back. 3 batches of messages were bounced on 9th, 11th and 12th Nov although I received a few messages between batches. Groups.io logged the bounced messages with the reason as:
mx001.tt.xion.oxcs.net: 550 5.7.1 Connection refused - [45.79.224.7] blocked by Vade Threat List -
OXSEU001_101 - https://postmaster-oxseu.vadesecure.com/inbound_error_codes/#_101
It appears that the Vade Threat List is incorrectly identifying these message as spam. They are not spam. Is this the same issue of messages not received as has been flagged up by various other users?
