Can't get net/smtp to send outside of LAN?

John N. Alegre [mailto:info@johnalegre.net] :

#if usr@domain is outside the LAN the mail never gets sent
#either if the code
#is run on 'localhost' or on a machine on the LAN with
#'machine' replaced by
#the IP of the SMTP server. I know 'machine' will serve as a
#SMTP host for
#mailers such as evolution or Mac OX X mailer because I use it
#for that all
#the time.

by default, for security reasons, most smtp servers do not allow relays. Specify in your smtp server the host IPs or networks you want to relay.

Exactly. That was the point of my earlier post regarding trying to send
SMTP messages through my company's Exchange box. Rather than return the
message undeliverable the box just discards the messages as disallowed
proxy attempts. But if I authenticate with the SMTP server with my POP
credentials the messages go out okay. This is something that happens
daily as I have several Ruby processes sitting there monitoring servers
and network hardware log files for critical errors. If they occur then
I am sent a cellular text message. If I don't authenticate my SMTP
session the messages would never go out...

Please see the [SOLVED] to this thread. It really had nothing to do with
any of what you are saying. It was an error on the part of my ISP. Code
as writen. No login, no password will relay just fine to my postfix / smtp
box on the same LAN.
