Hi,

In order for the TLS to work on the heficed . com server, I need to set up custom relayhost and transport.

I talked with their support team but we got stuck trying to get the right settings.

I need a relayhost to point to lon-tls . heficed . com:587

and a transport_maps = hash:/etc/postfix/transport

heficed.com smtp: lon-tls . heficed . com:587

postmap hash:/etc/postfix/transport

Thank you.
