Running Postfix 2.8.2
When I telnet smtp0.lightlink.com 25, and type 'help',
it says unknown command.
Thanks in advance for pointers to RTFM.

For help with SMTP commands, see:
http://tools.ietf.org/html/rfc5321
For help with Postfix:
http://www.postfix.org/documentation.html
The Postfix SMTP server does not implement the legacy Sendmail SMTP
help interface, this feature is obsolete.
Last time I looked (just now), RFC5321 stated:
"SMTP servers SHOULD support HELP without arguments and MAY support it
with arguments."
Not implemented, yes, and Postfix properly responds with a 502 response
code. Arguably not all that useful when implemented (e.g., as by
Sendmail). But neither "legacy" nor "obsolete" would seem to apply.
Is this reply nitpicky, and/or pedantic? Probably.
