I think problem is in this part: X-Original-Authentication-Results: gmr-mx.google.com; spf=neutral (google.com: xxxxx@xxxxx.sk does not designate permitted sender hosts) smtp.mail=xxxxx@xxxxx.sk If so, scam algo needs serious improvement. There is unfortunately no UI to set ignore flag for the further messages from the same user (!) Actual results: Email marked as scam Expected results: Email not marked as scam

That is not one of the things that trigger scam warnings. It's mostly links that do not go where they say they should go. To investigate, please attach a sample as .eml (In reply to Daniel from comment #0) > If so, scam algo needs serious improvement.

It's not like you would usually fall for a scam from someone you don't know. xref/dupe of bug 320351

Sorry, I can not post a private email. Only if you make this thread private, e.g. not indexable by Google and not public. Which you probably can't do. Anyway, I checked all the links in the email and they are regular links (e.g. text of the link is the same as the a href URL). Mostly, just standard google groups unsubscribe etc. links are included and one bit.ly link.
