Hi!
I'm new in the list, so excuse me if I send something that is already posted. We needed to configure a relay host for our domain(eg: example.com) and all subdomains as well(eg: a.example.com, a.b.example.com) so we set the relay_domains parameter to "example.com", which don't work at all for us(the host relays mails from the example.com domain but not for any of the subdomains). We do some tests and the only way for us to acomplish this was adding a dot to the beggining of the domain at relay_domains(eg: .example.com). This is a normal behaviour? The postfix documentation says that this effect is achieved without the need of place the dot. There is another way to perform this? Thanks in advance!
