Hi, I’m trying to setup an internal postfix mail server for a very specific use for a client. They need to REJECT all mail that is attempted to be sent with a MAIL FROM: value of anything other than an address at “good-domain.com” (for this example). If someone was to MAIL FORM: ad...@google.com for example, it should be rejected.
I thought I could do this in a sender access file within smtpd_sender_restrictions, but I’m not having much luck. File: /etc/postfix/main.cf smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/insiders File: :/etc/postfix/insiders *@good-domain.com OK *@*.* REJECT However when I telnet to the SMTP service, I can MAIL FROM: andy address/domain I want and postfix proceeds. Can anyone suggest where I’m going wrong??
