Hi, I have a server running on Debian 9 with latest ISPconfig server My server is running fine & have been receiving / sending emails But the problem that I have not been receiving email from a known server & email id starts with [email protected] What changes should I make in my postfix file Please help Thx@
Open /var/log/mail.log and search for a line containing that email address. On that line or a few above/beneath there will probably be a line that tells you what's wrong.
