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.
