Here are the pre-requisites: - You must have a solid understanding of SMTP, DNS, etc. - You must have one or more fixed IP addresses. - Your ISP must be willing and agree to delegate your IP address(es) to you or to whomever is going to handle the DNS for your domain. A call to your ISP's DNS provisioning department may typically be all that's required. - DNS must be set up correctly. - Your email server must be set up correctly. - Your own network must be secured. - Your DNS and email servers must be available 24-7/365. If all the above can't be met, you have no business sending or receiving email. If you want to try and PASS GO and collect the $200 by skipping one or more of the pre-requisites (common enough, it seems), prepare yourself for some heartache, and be aware that you're likely to cause or participate in grief for others. Put simply, email is one of the more complex and challenging things you can do. If you don't have the knowledge or technical expertise, but feel confident you can master the fundamentals and progress from there, be prepared to spend the next month or two or three slogging through reading RFCs to do so. If you do, know that your work has just begun, and the hard part is just around the corner. ;-) > Also looking for advice on which software would serve me bet in this > instance. I'd suggest setting up an internal test network and deciding for yourself. For example, setting up a number of FreeBSD jails, each with its own running installation of sendmail, postfix, qmail, etc. would be a good approach, and may more useful than relying on the opinions or recommendations of others. -- George
