Dear mail operators,
Since at least September 17th, 2024, we receive a lot of unsolicited
messages from SendGrid. I forwarded five to ab...@sendgrid.net, but
there was no reply and the problem persists. Today at least five
messages from xvfrkpcc.outbound-mail.sendgrid.net [168.245.19.204]

Ha, I guess you proved Gellners point of (me) not actually knowing anything

You are right, far too many companies big enough to at least get a
dedicated IP, instead of a shared IP, they should have custom PTR's, and
*shudder* their SPF records included all of SendGrid, so needless to say
