I wrote an article about spam filtering sometime ago. Context was "Spam Filtering should not have any False Positives, ever!". If anyone is interested they can read it here: https://www.linkedin.com/pulse/20141202174235-36852258--spam...

#32I run my own mail server with full SPF, DKIM and SRS, routing the mail through a relay at a reputable VPS provider on high-reputation IPs. Over the last few months, there seems to be this pattern where if I email someone @gmail who I've never mailed before, they don't seem to ever get it. I wonder if this is the issue.
This is one of the reasons I use Google Apps for Business for email (that and I find running mail servers tedious) as deliverability is consistently simpler.

#33very funny, right after I saw this, I decided to check my spam folder just to see if anything important has been filtered out, and I saw an email sent by google marked as a spam: this email is sent by google when logging in google account from a new machine. they tag their own email as spam ... Hi xxx, Your Google Account xxx@gmail.com was just used to sign in from Chrome on Windows. Don't recognize this activity? Re…
At least their filters are as impartial as they're inaccurate and overly aggressive...

#34I could see 20% false positives on spam for Linus equating to 0.1% of false positives across the board since I suspect the people emailing Linus are 200 times more likely to be running their own mail server than the general public.

Assuming non-gmail servers are spammers is a pretty epic fail.

The hilarious -- or maybe really sickening -- thing is that Gmail itself has also become a much larger source of spam than it used to be.
Those of us that are running mail servers are really not loving Google at the moment.

I agree completely. Wasn't there a thread here a just few days ago discussing Gmail consistently marking personal mail servers as spam? EDIT: Found it. https://news.ycombinator.com/item?id=9855030
I use DKIM and have Reverse DNS + SPF and gmail likes my email just fine.
However, previous to setting all that up gmail would commonly mark my messages as spam. I haven't tested it in the last few days.

What about using it as one of many criteria (maybe whether the email seems to contain gibberish being another, which patch files might be classified as).
Re: Dear Google Mail Team
#38I guess we'll just go back to manually making filters.

Having to use a Google product instead of your own mail server, in order to have your email delivered to Google customers, sounds like anti-competitive business practices to me. You'd think they'd be a wee bit more careful with something like that given EU interest in them...
