I have a site running on CentOS 5.4 through Amazon EC2. Unfortunately, Amazon has had nothing but trouble with their entire IP range getting black listed from spam tracking services regularly. I need a mail server, so I setup an smtp server elsewhere that I want to send to, but I can't just send directly to it through PHP because the direct smtp request is way too slow. What I want to do is relay through sendmail, but I've never used sendmail before, so I have no idea how to configure it. All I want is for all emails sent from localhost to be relayed to one specific external server, but I don't know how to do that. I tried to find a tutorial online, but couldn't find anything that was particularly clear as to how I go about doing that. Can anyone help me out?

The sendmail feature you need to configure is mailertable. Here are simple config instructions after a base install of Sendmail. Mailertable: http://www.cyberciti.biz/faq/force-sendmail-to-route-mail-to-specific-hosts-or-mailserver/ Sendmail full Monty minus mailertable http://www.howtoforge.com/squirrelmail-configuration-easy-steps-squirrelmail-sendmail-apache-redhat-centos-fedora If this doesn't work for you I'd recommend using installing webmin to configure the install. I would I highly recommend configure your firewall for outbound email. | |||

As long as you are sending transactional emails, look at this SMTP Relay Service. No limit on emails that can be sent and Free option is available. | |||
