Subject: Re: 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.

kind regards -botp
