mailx how add ISP as SMTP

[Shwick2]

Ubuntu 8.04

How do I configure mailx to use my ISP's SMTP server? Also I have to enter a username/password.

mailx is only a local mail user agent. It will drop all outgoing mail into the mail queue used by your system's mail transport agent (postfix by default on ubuntu), and it is this which does the heavy-lifting work of sending the mail out.

So, to configure postfix to use your ISP's SMTP server, put this in /etc/postfix/main.cf:

relayhost = isp.smtp.server.domain.name

and then reload postfix with:

postfix reload
