I have a need to test network throughput for SMTP traffic on Fedora and I'd like to configure postfix to accept incoming e-mail from clients and drop them. How can I go about that?
A postfix mailing list would be more appropriate?
In any case, look at man 5 access.
In /etc/postfix/access: 1.2.3.4 DISCARD message go bye
1.2.3.4. being the IP address of the client (see the man page for loads of alternatives)
then: # cd /etc/postfix # postmap access
You might need to configure postfix to look at that access file.
Something like the following in /etc/postfix/main.cf: smtpd_client_restrictions = check_client_access hash:/etc/postfix/access,
