Hi Sidney,
This leaves me wondering what I should fill in there. The name of the
action? The name of the server? Any random label?
I think the relevant part of the documentation is the description of the
host option in smtpd.conf(5):
host relay-url
Do not perform MX lookups but relay messages to the relay host
described by relay-url. The format for relay-url is
[proto://[label@]]host[:port].
[...]
The label corresponds to an entry in a credentials table, as
documented in table(5). It is used with the “smtp+tls” and
“smtps” protocols for authentication.
Does this clarify the meaning of "label"?
Best regards,
Matthias
