Hi, Geoff.
Yes, at some time in the recent past, GMail started inspecting the header FROM:
field as well as the envelope sender. I noticed it myself just a couple of weeks
ago, when I was revamping our sender-rewriting-scheme code. I now put the SRS
address into the headers as well as the envelope, and use the Reply-To: header
to direct replies.
I extract the decoration (if any) from the original email and create something
like
MAIL FROM: <srs-blah-blah-b...@example.com>
RCPT TO: <u...@gmail.com>
From: "Joe Blow" <srs-blah-blah-b...@example.com>
Reply-To: joeb...@example.com
Resent-From: originalrecipi...@example.com
To: whatever the original said
for the headers. It's messy, but it works. The only real drawback is that some
users get confused by the SRS email address, and/or have filters in place that
auto-direct incoming mail to specified folders. However, since GMail no longer
accepts forwards done that way, the filters are toast. It's Hobson's Choice:
Either embrace SRS and violate the RFCs (create a new email entirely), or stop
trying to forward.
I haven't seen rejections from the other big providers yet, but I suppose
they'll all fall in line eventually.

Subject: [mailop] change at gmail???
> I noticed a change at gmail in just the past few hours...
Previously mail that my mailing list software sent to gmail with an
envelop sender set to list-boun...@mydomain.com and the From: field
being From: u...@yahoo.com worked just fine.
Now these messages are bounced with a DMARC error.
Am I just confused or did something at google change?
Does mailing list software need to rewrite the From field also now?
Geoff
