It's very probable that Gmail files these messages to recipients' Spam folder. It happens very often (more often than not) with my messages as well. People often tell me they can't find my messages in Spam folder, but I think it's just their inability (lack of skill?) to do so, rather than the actual lack of message in the folder, because I have myself set up a few accounts on Gmail for test purposes, and always when I sent anything to one of these accounts and the message wasn't in inbox, I was always able to find it in Spam, the message never just "disappeared". -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop

I have had exactly the same issue about a year(?) ago. All of a sudden, when I sent a message to - if I remember correctly - 7 recipients, of which 5 were on Gmail, I got this rejection message and the message, as well as subsequent ones, even if sent to only one recipient, were deferred for many hours. The issue lasted for maybe a week or two, then disappeared on its own. On average, I send maybe three-four messages to Gmail users per day IN TOTAL. Sometimes I don't send any message to Gmail at all even for two-three days, so the message about "unusual rate of unsolicited email" seems pretty ridiculous in this context. Similar to you, I have SPF, DKIM, DMARC etc. all in place, valid PTR, IP not on blocklists (except occasionally the entire ISP's netblock falls onto UCEPROTECT level 3), I have owned this domain for multiple years. I have also registered my server and domain on DNSWL. All this doesn't help in any way. I have also my domain registered in Postmaster Tools, but it doesn't show any data due to too small number of messages. I guess Google's mail system is just tuned towards big senders who send large amount of mail and totally doesn't "know" how to handle small senders which send only a handful of messages. If I were Google, I would just exempt the small domains (those that are too small to show up in Postmaster Tools) from most "sophisticated" checks that their system is probably doing, which may work well for large senders, but for small senders they just lead to absurd FPs like the ones described here. But for some unknown reason, Google doesn't want do do that. So for a small sender, it becomes more a random thing whether their mail will be accepted by Google or not. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." ___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
Re: [mailop] Single deliveries are good for you was, Gmail now deferring
It appears that Michael Orlitzky via mailop said: >This will work, but you probably don't want to make your entire MTA >inefficient just to appease Google. Actually, you do, and it's not just Google. I've seen stats that say that the average number of recipients on legit mail is about 1.2, keeking in mind that bulk mailers all do single deliveries since they customize each copy of the message. A message with a dozen recipients in the same SMTP session is a very strong spam signal. So don't do that, do single deliveries like everyone else does. It occurs to me that one of the reasons I don't see the delivery problems that a lot of you do is that I use qmail (now heavily patched of course) which has always done single deliveries. It works great. Inevitably when I say this, someone will make huffy comments about how horribly inefficient single deliveries are. It was a silly argument when qmail started doing it 25 years ago and it's infinitely sillier now. The total amount of bandwidth every mail system in the world uses is a rounding error compared to what we use for cat videos. Since mail systems do several deliveries in parallel, single deliveries are not much slower than multi-recipient, and they're infinitely faster when they get through and the others don't.
