Ha! More interesting information.... Those are all things you'll have to consider whether or not you trust google over, say, Cox ;-) . Obviously it will be more expensive to host it all on your on server. If you're buying from, say, slicehost, you have to trust them as well though to a somewhat lesser degree. If you stand up a physical box at a co-lo, that can be quite expensive. Also, managing a "real" mail server (and DNS) can get very complicated very quickly. How well do you understand SMTP and related protocols, mail filtering (because you will need to filter), DNS and MX records, the various spam blocklists, and security/patching? Unfortunately, it's not as simple as typing "apt-get install postfix"; you really need to have a good understanding of the network protocols involved and how you are going to address spam and virus traffic. There are numerous discussion about perfect mail server setups using various debian distributions and combinations of mail server software (postfix, qmail) that can be easily found using ... well ... um... Google. Please don't interpret this as me encouraging you to avoid setting up your own mail server. I'm just pointing some things to start researching if you choose to learn about it by doing. Things to google on: postfix, qmail, SMTP AUTH, TLS, submission port 587, tmda.sourceforge.net, spamassassin, clamav, amavisd, MX records, Sender policy framework (http://www.openspf.org), etc ,etc ,etc :-) |
