Count me too as someone with a tiny server that Gmail automatically files in spam with apparently no reason. There are so few mails sent there (at most, 7 mails *per month*, often none at all) and seeming so futile, I didn't even dedicate time to that. It's slightly annoying, though.
There is people that download the mails and never even see what went into the spam folder. I have also warned people that they might receive my emails into gmail spam folder, that they didn't think would happen. Receiving time after that a late reply excusing himself noting that it went indeed straight into spam. It doesn't seem to be in a particularly bad neighborhood, either. The most relevant event there was a bad apple almost two years ago that resulted in a shortly-lived /24 spamhaus listing. Maybe some system is remembering such old event (from *another* IP address) and considering that enough to consider as spam. Or it could be using fairy dust. It is perhaps too easy to moan on how *Google* should be doing things, and I'm probably not qualified to voice an opinion on their default approach for cold-mails received from sources with no reputation. However, the part that I find odd is that, after an account actively engages with a recipient, it would 'forget' it and still go to spam, as reported by Jaroslaw. I would expect that after Alice sends (or replies to) an email to Bob, absent a newer user signal (such as later marking it as spam), mail from Bob would _not_ go into Alice spam folder. Especially if it is a reply to a message from Alice. There are clearly indexes in place for sender and message-ids in gmail, so checking those, and that overriding the vague reputation that seems would be in play here, would appear to be the proper way to go.* Maybe I should perform some tests to see how things seem to work now. Best regards * I am a bit conflicted on the proper behavior if it detected clearly malicious content, though. The user may be clearly expecting news from that 'overseas banker', but if it was actually a fraud... _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
