Fixed: PowerMTA 550, 5.7.1 relaying denied for recipient

For security reasons, PowerMTA does not allow external relaying by default

The default configuration only allows messages to be sumitted from the local IP address. 

In order to submit messages for delivery from a different host, you will need to enter its IP

address(es) into the configuration file by creating one or more source entries and

specifying the always-allow-relaying directive.

When configuring PowerMTA for outbound, you want it to accept e-mail from your feeders for
all domains, by using always-allow-relaying.

Relay-domain and relay-address directives in the configuration file are

really only useful when PowerMTA is used to handle inbound traffic. That allows you to

specify the domains in messages which PowerMTA is to accept from any sources.
