Calendar invitations being sent to SPAM by built in filter

I have found that my calendar invitations (to a GMail account) are now going to SPAM. From trial and error on both my GMail filters and EMClient rules, I have narrowed it down to one particular “rule” that is causing this. However, the rule is a built-in EMClient one identified by the “highlighted” line in the image.

Becuase that rule is not editable, I have no idea what is causing this and what other SPAM filters would be missed if I deactivated this rule. Any help appreciated.

Your screenshot highlighted Spam Filter (1) (1) etc is not an eM Client default rule and sounds like a custom modified rule. Dblclick that highlighted rule to view it.

There is a default POP just called Spam Filter “usually the first one displayed at the top” as per the screenshot below that carnt be edited, but any other rules can be edited or deleted. The default POP filter doesn’t normally cause that issue.

Suggest for troubleshooting purposes to “disable them all” and then see if everything works ok.

If it then works ok with all the rules disabled, then suggest next to “delete all the Spam Filter (1) (1) rules” and create them again as new “and also name each one” so they are not all called the same name. Create new rule documentation

If disabling all rules to test still has the same issue, then could be “you might have accidentally added the Gmail account or Gmail domain in the Blacklist”.

To check the Blacklist in V10 go to “Menu / Settings / Mail / Blacklist & Whitelist”. Then click “Manage Blacklist” at the bottom.

Thanks. I had already unticked all the system rules to try and figure out which was causing the trouble and I identified the one rule which was the highlighted one in my OP. I had also checked the blacklists and neither domain nor address was present.

Although since then I have found that different rules drum responsible for spam labelling different calendar invitations when from the same sender!

It’s a strange one so for the moment I have decided to disable all the system rules and leave it Gmail to manage spam.
