My NetBSD box is a NAT inside server and has not a public IP or DNS name. Via sendmail and mail, I can send out our message to somebody, but receiver can't reply to me. So I want to use a outside SMTP account. But I don't know how to configure them. Where do I should configure my SMTP server, account and password? I know KMail can do this work, but I have not X. Who can help me?
Thanks!
