Sure, I can understand that, but I don't like it and I don't really want to move to another hosting provider at this time, unless people have a good suggestion? And how long before that provider gets completely banned as well? And what VPS provider do you recommend? So right now I'm trying to learn how to write a milter to re-write email sent via a specific transport. So I have setup my transport like this: # Added to deliver mail to charter.net, 20221202 charter unix - - y - - smtp -o smtp_tls_wrappermode=yes -o smtp_tls_security_level=encrypt -o smtp_generic_maps=hash:/etc/postfix/sender_charter -o header_checks=pcre:/etc/postfix/charter_header_first -o smtp_header_checks=pcre:/etc/postfix/charter_header_second -o myorigin=charter.net And I have it properly trying to send the emails, but I get bounced with: <jstof...@charter.net>: host mobile.charter.net[47.43.18.12] said: 550 5.1.0 <j...@stoffel.org> sender rejected (in reply to MAIL FROM command) so I think I need a milter to re-write my From: header on my outgoing emails to be jstof...@charter.net. Should be simple, but how to tie it in isn't quite clearcut to me yet.
