I'm not seeing deferrals but some of my users are reporting that they're
not seeing emails coming from my play by email service. I've double
checked the logs and gmail is accepting the messages. So anything
happening to user mail is under the covers on the gmail side.

Gmail recently changed how they calculate domain reputation within the last two
months. Domains that didn't encounter issues before are now experiencing
problems.
I'm not entirely certain about the specific changes on Gmail's end, but I have
observed these issues across multiple client
I've added a gmail.com-specific transport, with a recipient_limit set to 2 (so
it does not become per-recipient instead of per-domain), a concurrency limit of
1 and a 10s rate delay. For the amount of email we send this should not be
problematic. I'll see if we can then build up a better rep

If that's what the problem is, then that can easily be set with the
following Postfix setting without the need for customization scripts:
default_destination_recipient_limit = 1
Documentation for this setting is available at:
I have nearly the exact same setup and usage you do. I got the same deferral
when sending an email to <20 friends, of which about 15 were on Gmail. Exactly
the same results as you got.
Fortunately, I found I could schedule one recipient at a time (using opensmtpd)

Unrelated to the question of whether or not @ merits escaping or quoting...

Thanks all. I'll answer comments here in one email.
I use a single mail host (mail.simonandkate.net) as MX for a range of family
domains on a fixed/business IP address through a high quality ISP (not a
variable IP, not in a dial-up block). I've had the same IP address for about 7
years. It has
I've seen problems like this because of ISP listing large net locks as "dialup"
and not supposed to send email directly.

the at ("@") symbol counts as a "special" character that's
categorized seprarately from "atext," and an example in Appendix A
demonstrates quoting when a special character is present:

It's definitely worth it to run your own eMail system (in my
opinion). I think people should be able to do this if they want to,
although one of the challenges that sometimes arises is which IP
netblocks their eMail servers are in.
