Hello. I'm trying to set up an SMTP gateway for a subdomain (subdomain.domain.com) of a larger organisation (domain.com). The host is declared as the MX for foo.domain.com. I'd like it to be able to collect mails sent to @foo.domain.com, and redispatch them to individual hosts inside this subdomain, for specific processing.
Here is my main.cf file: aemon_directory = /usr/lib64/postfix inet_interfaces = all mynetworks = 129.175.144.0/24 172.18.213.0/24 195.83.212.0/24 195.83.213.0/24 193.51.235.0/24 193.51.236.0/24 193.55.250.0/23 193.49.212.0/23 193.49.213.64/26 195.83.212.48/28 myorigin = $mydomain delay_warning_time = 4h smtpd_banner = $myhostname ESMTP $mail_name mydestination = $myhostname $mydomain relayhost = smtp.domain.com alias_maps = hash:/etc/postfix/aliases alias_database = hash:/etc/postfix/aliases Here is my alias file: foo: [email protected] With this configuration, a mail sent to [email protected] is accepted, then forwarded to host.subdomain.domain.com as expected. But instead of directly sending it to host.subdomain.domain.com, it is immediatly relayed to the relay host, smtp.domain.com, whereas it is supposed to be a local mail address. I tried to add mydestination to parent_domain_matches_subdomains, it doesn't change anything. I found than using an explicit transport map fix the issue: host.subdomain.domain.com smtp:host.subdomain.domain.com But it's a bit painful to list every host inside subdomain.domain.com there. I'm obviously missing something trivial here, but I can't understand what exactly. -- BOFH excuse #300: Digital Manipulator exceeding velocity parameters
