I'm trying to setup an easy mail server to support my "lost password" function in my website.
I'd like to know if Exim is good or not, or is there any better solution?
I would also like to know that it isn't easy to manage an smtp server (such as blocking junk mail, or being hacked, etc), does setting up a send-only mail server cause any security issues?
Thanks!
Simple example to setup postfix with satellite SMTP
install postfix
sudo aptitude install postfix
configure postfix
sudo vi /etc/postfix/smtp_auth
add your smtp authentication information in /etc/postfix/smtp_auth:
smtp.foo.bar user@host:password
and generate the postfix lookup table file (/etc/postfix/smtp_auth.db) using
sudo postmap /etc/postfix/smtp_auth
add the relayhost (outgoing smtp server e.g. smtp.foo.bar on port 587, depending your relay host info) information to /etc/postfix/main.cf:
relayhost = [smtp.foo.bar]:587
add the following lines to /etc/postfix/main.cf in order to enable smtp-auth for outgoing mails:
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/smtp_auth
smtp_sasl_security_options = noanonymous
restart postfix
sudo service postfix restart
