Hi all, I looking for a way to allow relay on my postfix server from a specific domain and from a specific IP (one or range). In the postfix documentation, I see this in smtpd_sender_restrictions documentation : check_sender_access and check_sender_a_access I also see a smtpd_sender_restrictions in postfix set by ISPConfig with a directive check_sender_access that point to a regex "tag_as_foreign.re" My question : 1. Is it possible to configure this type of relay directly in ISPConfig, if Yes, how ? 2. If No, has anyone already implemented this type of configuration or do you have any recommandation ? Thanks in advance, Yannick
In my memory, we can relay for recipient domain not for sender domain ? I was using this functionality to use my server as MX Backup.
Based on the postfix documentation, I can set smtpd_sender_restrictions = check_sender_a_access hash:/etc/postfix/sender_IP_checks, check_sender_access hash:/etc/postfix/sender_checks but in this case, I don't have a specific domain and IP control.
I think it's the sender domain that you can set in the per domain relay settings of the email domain.
