Some IP ranges (particularly cloud-service instances which spin up & down and may have different hosts appearing at the same IP addres) also have trouble. For mine, I had the instance running (on the same IP) for a year or two before I decided to move my mail functionality there, so I knew it didn't have a history of recently spamming other hosts. Similarly, home ISP ranges are also often rejected because the rDNS resolves to something auto-generated rather than the actual domain-name. Just in case you're looking for other tilt-bits that might be used when rejecting messages. -tkc

I found that I had to both set my SPF for the sending-server (in my case, my VPS is the sender, rather than outsourcing to a smart-host elsewhere), and I need to set up DKIM (putting my server's public key in DNS, and then signing outbound mail) to get the best results with Gmail. Otherwise, things kept ending up in Spam -- even when I was sending to my test Gmail account and the sender (me) was a known contact in the Gmail account, and back-and-forth replies had all the right in-reference-to headers set properly. I haven't yet messed with DANE, but SPF+DKIM seems to be enough to make Gmail less grumpy. Gmail is a bit fastidious, rejecting messages overzealously. But they're the 800lb gorilla in the game. -tkc

Try to get removed from it. Good luck. It sounds like the mail server you are using needs a configuration change to stop backscatter.

It's just that when spammers use gmail to send spam, gmail happily and correctly DKIM-signs the outgoing spam. Gmail only protects gmails users from receiving spam. It doesn't stop them sending spam. At least, that's what seems to be the case. cheers, raf
Re: A bit off-topic: problems with sending to a Gmail user
> PS: maybe there is an option in gmail for users to whitelist senders > from whom they want to receive mail? Yes, sort of. There is no absolute whitelist, but there are two things a gmail user can do to make it much less likely that mail from a particular sender is marked as spam. 1. Have that sender in their contacts. 2. After receiving an email from that sender that does go to spam, click "not spam" on it. Sometimes you can arrange this by private messaging with someone as you send them email, and have them check spam for the email you just sent and click "not spam" while you're talking. -- Cos

[more off-topic/rant] Isn't it nice how Google et.al. enforce things which are neither mandatory nor really useful to "fight spam"? All the spam I get at $WORK is from gmail and it has passed all of those "requirements" -- but the "investment"/"loan"/... spam/scams are not filtered at all by Google themselves (hey, why should they do outbound spam filtering? it cost them money and why should they care? it's not like anyone important would block gmail -- but Google rejects mail coming to them due to bogus reasons). "Solution": ask gmail users to switch to other services which do not have so many "false positives". PS: maybe there is an option in gmail for users to whitelist senders from whom they want to receive mail?

A bit off-topic: problems with sending to a Gmail user
Hello, I know, it's not the fault of our beloved mutt, but maybe someone is or was in the same problem and knows a solution... We (my family) are member of a fisherman association and I have to send mails to one of the head members in charge for youth training. He has a Google mail account as and any mail gets rejected by Google with the response below. Any idea what I could do?
