[Evolution] new user - spam issue

[Ludo Beckers <lazylew gmail com>]

Hi, 

I just installed Evolution for the first time.

Version: 3.28.5-0ubuntu0.18.04.2 on Linux Mint 19.3 Cinnamon

So far have put two gmail addresses as accounts and it looks ok.

The issue I have is that one of the two suddenly reports 175 old mails as being spam.

This happens inside the gmail-account, but right after the Evolution-install, hence the thought the issue is related.

When I mark those messages as safe, not long after the same will happen again and again - those mails end up being marked as spam.

What to do?

Greetings,

Ludo
