Same here. MIT has the only mail systems that reliably and deliberately
break bounce handling so badly that it defeats VERP. I have a bunch of
majordomo lists, and each message goes out with an envelope address like:
majordom-virt-list-user=domain@iecc.com
where virt identifies the virtual domain where the list lives, list is the
list name with punctuation squeezed out, and user=domain is the user@domain
recipient address. It happens that the mail host is named ivan.iecc.com, so
MIT's mailer rewrites bounce addresses to:
majordom-virt-list-user=domain%iecc.com@ivan.iecc.com
For one thing, I don't permit the percent hack and don't know anyone else who
does, since it practically begs spammers to use you for a relay. For
another, although ivan.iecc.com is a host, it's not a domain that accepts
mail because other than MIT's brain-damaged bounces, 100% of mail to that
domain is spam to addresses scraped from usenet headers.
I have daily security logs that show me attempts to relay through here, and I
can recognize the MIT bounces and handle them by hand, but I don't understand
why they think what they're doing is a good idea.
