Hello,
I am managing a Postfix mail relay service in our internal network. The
relay itself is more permissive than the downstream SMTP server. So it
is possible, and indeed it regularly happens, that my relay accepts a
message which is subsequently bounced by the downstream server. There is

If you're willing to parse headers, then all the information that
you need is already available. There is no need to add yet another

Hi,
I have an issue that I can not resolve at my work environment.
When I use commandline mail, my e-mail gets delivered.
However, when I use a mailer (like sylpheed) to use localhost, it does not get
delivered. I have SMTP port set to the default, and this same setup works fine
