Recently, my paranoia levels have been ratcheted up by reading about companies' treatment of their users, along with an increasing awareness of my powerlessness with respect to most content providers. I therefore curbed most online activity and have attempted to host those services I used on my own server, in most cases living without when I didn't succeed.
Two months ago, I attempted to install postfix and dovecot on my Arch box in order to be able to host my own mail. Naively I thought that all I needed was the right software and a dynamic DNS address. In other words, I thought it would be as simple as setting up a web server.
Naturally, I found out that most anti-spam software is leery of mail from dynamic DNS hosts who do not have rDNS and PTR records set up, that they preferred DKIM mail, etc.
Seeing as these involve even more effort, I thought to ask the enlightened members of the Arch community which solution they would suggest me to use, because I trust you to have made intelligent decisions in this matter and believe you understand this outlook. Also, I've seen many users with email addresses issued by their own domain, which leads me to believe some of you may have gone through this before.
The alternatives I'm aware of are: 1) Do what most people do, and just sign up for webmail, paranoia demanding me to download all email every day. Possibly alias the domain by routing everything through postfix first. 2) Host my own server, paranoia demanding multiple redundant backups. 3) No email - Knuth style
Pros: 1) Very reliable, better support, and non-crazy 2) Gain vast amounts of power over my email 3) Less distraction, no effort at all
Cons: 1) Less control, more black box. Is aliasing even possible? Too many providers - which to choose? 2) Hard to maintain, can crash at any moment, will drive me to early grave 3) Harder to keep in touch with people this way, harder to check what's going on
Which do you suggest? Do you have an alternative?
Thanks in advance,

I chose the 2d alternative, but I have a fixed IPv4 adress since I host my contents on a dedicated server, so I didn't met theses dynamic DNS problems. For the backup part, a simple script using rsync in crond.whatever will take good care of it. Sometimes, your IP can be registered as "spam adress" on some DNSBL, but most of the time you can ask to be removed from this list by proving you own that IP. If you tend to be paranoïd, this solution has some drawbacks : - Security will sometimes make you sweat (Unless your are a security pro) - What guarantees you that your provider doesn't peek in your hard drive? To answer to the second problem, when I have some really critical files I save them on an encrypted partition that is closed most of the time. Hope this helps -- Garrik
