Hello! We had the situation that we got mail that wasn't RFC-compliant and our listserv rejected it.
MAIL From: <[email protected]> Listserv replies to the From: header and not to the Return-Path. It doesn't see MAIL FROM because the mail is being piped to the application, but it could use Return-Path. MAIL FROM: <> is being used, so it is being detected as a bounce. Is my guess right that this is the FortiNet bounce verification system? https://help.fortinet.com/fmail/archives/3_0/fortimail-admin/wwhelp/wwhimpl/common/html/wwhelp.htm?context=FortiMail_Online_Help&file=FortiMail_Online_Help-12-38.html Is it ok that Listserv behaves like that? -- kind regards Marco Send spam to [email protected] _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
