Michael had asked for feedback to confirm that an asterisk is not an allowed localpart character. It is an allowed localpart character. Hence why I stated he would be disappointed.

I'm definitely disappointed by the giant chunks of excess HTML links and previews added to your reply, for sure. But the page you linked to clearly says that the asterisk is allowed in the username portion, so nothing to be disappointed about there. Not sure if perhaps you misread it just now.

The RFC allows you to put a LOT in the localpart without any sort of fanfare, and you can do almost any stupid thing you want as long as you quote it. ________________________________ From: mailop <mailop-boun...@mailop.org<mailto:mailop-boun...@mailop.org>> on behalf of Al Iverson <aiver...@wombatmail.com<mailto:aiver...@wombatmail.com>> Sent: Friday, January 11, 2019 10:45 AM To: Michael Peddemors Cc: mailop Subject: Re: [mailop] Mailing List Address Formats.. Return-path headers using VERP in this way, with asterisks in the username part like this, can be traced all the way back to LISTSERV in the 1990s. It's a long standing practice. If you block based on this, you'll block a few spammers or commercial mailers who used or use LISTSERV, or who rolled their own mailing list software in a way where they copied the VERP styling exactly, but you'll also probably block lots of academia and random non-spammy discussion lists. When I worked for Digital River approximately 150 years ago, we had an internal platform that had its own databases and UI for list management and campaign configuration, and then when you hit "send" an email template was built that was then handed off to the LISTSERV server which then did all the building of the messages. The Return-Path header for these messages was always of the format owner-nolist-x-y*username**domain*-suffix@sender.
