> I guess Google's customers are just more trustworthy...
I wish. I've been having issues with being sent to spam when replying to a colleague on the same ___domain which is on Google. The email never left their servers, everybody was authenticated, and the emails were within an hour of each other, so it's pretty obvious that it's a reply. Still: off to spam it went.
We now have a filter rule to always consider our own ___domain as not spam, because it's just too unreliable otherwise.
Note that your filter might be breaking an important security feature:
If you get an incoming email “from” yourself and it is not marked as spam, it will be put into your sent label.
At least one person claims to have been incorrectly fired because of this. Their employer found incriminating emails in the person’s sent box, and considered it a closed case.
That's interesting, do you have a link for that case? I don't see why it would get put in the Sent folder, but if it does, that might certainly lead to confusion.
