Hello. I’m moving mail from some server (where was DirectAdmin and I don’t have root access) to other, where is Virtualmin and I have problem with reject_sender_login_mismatch. I setted up in /etc/postfix/main.cf:
smtpd_sender_restrictions = reject_unknown_sender_domain reject_non_fqdn_sender reject_unknown_address reject_sender_login_mismatch reject_unauth_pipelining permit
smtpd_sender_login_maps = hash:/etc/postfix/virtual
From roundcube i can send mails, because he translatting login from email@example.com to user-domain.tld, but if I use Outlook/Thunderbird with firstname.lastname@example.org login, after send e-mail i got respond:
Aug 8 03:14:52 olnet postfix/smtpd: NOQUEUE: reject: RCPT from unknown[x.x.x.x]: 553 5.7.1 email@example.com: Sender address rejected: not owned by user firstname.lastname@example.org; email@example.com firstname.lastname@example.org proto=ESMTP helo=
Is any solution to fix it without every time after create email change config from console and without go to customers and change them logins in their computers?
