The problem with PTRs is that I run several domains from the one IP
address, and PTR can only point to one of those. It costs money to get
more IPs, my pension is barely coping with the recent cost of living
increases.

Though I don't really need to send email from the metaverse.farted.net
one, it's a joke domain for my Zuckerverse parody, coz OpenSim does
almost everything Zuckerberg claims is coming in his future metaverse.
He set a low bar, I had trouble getting down to it. I'm 61, I don't
limbo as well as I used to.

As for the general topic of gmail and mailing lists, many years ago when
I used to do that I had to setup a read only and a write only gmail
account on every list. Coz otherwise gmail would decide to not send back
to me anything I wrote. Now I use my own email server.
