You will need to press enter a couple of times. Doing this typically once per week may be a chore, and it's not completely foolproof, but it at least provides some degree of confidence that there have been no intrusions.

Even when using Freedombone metadata analysis by third parties is still possible. They might have a much harder time knowing what the content is, but they can potentially construct extensive dossiers based upon who communicated with your server when. Metadata leakage is a general problem with most current web systems and it is hoped that more secure technology will become available in future. But for now if metadata protection is your main concern using Freedombone won't help. Even when using Freedombone metadata analysis by third parties is still possible.

* How do I create email processing rules?
You can administer email in the traditional manner by editing folders or procmail rules, but for convenience some commands are available to make that process simpler. See the relevant manpages for more details.
| freedombone-addlist | Adds a mailing list |
| freedombone-rmlist | Removes a mailing list |
| freedombone-addemail | Transfers emails from an address to a given folder |
| freedombone-rmemail | Removes an email transferal rule |
| freedombone-ignore | Ignores email from an address or with a subject line containing text |
| freedombone-unignore | Removes an ignore rule |
Spamassassin is also available and within Mutt you can use the S (shift+s) key to mark an email as spam or the H (shift+h) key to mark an email as not being spam. So by using a combination of email rules and spam filtering you should be able to avoid any spammers or trolls.

Almost everywhere on the web you will read that self-signed certificates are worthless. They bring up scary looking browser warnings and gurus will advise you not to use them. Self-signed certificates are quite useful though. What the scary warnings mean - and it would be good if they explained this more clearly - is that you have an encrypted connection established but there is <i>no certainty about who that connection is with</i>. The usual solution to this is to get a "real" SSL certificate from one of the certificate authorities, but it's far from clear that such authorities can be trusted. There have been various scandals involving such organisations, and it does not seem plausible to assume that they are somehow immune to the sort of treatment which <a href="http://en.wikipedia.org/wiki/Lavabit">Lavabit</a> received. So although most internet users have been trained to look for the lock icon as an indication that the connection is secured that belief may not always be well founded.

Welcome to the world of email. Email is really the archetypal decentralized service, developed during the early days of the internet. In principle anyone can run an email server, and that's exactly what you're doing with Freedombone. Email is very useful, but it has a big problem, and that's that the protocols are totally insecure. That made it easy for spammers to do their thing, and in response highly elaborate spam filtering and blocking systems were developed. Chances are that your emails are being blocked in this way. Sometimes the blocking is so indisciminate that entire countries are excluded. What can you do about it? Unless you control the block list at the receiving end probably you can't do anything. There is zero accountability for such blocking, and you can't just contact someone and say "hey, I'm not a spammer". This system works well for the big internet companies because it effectively centralises email to a few well-known brand names and keeps any independent servers out. Welcome to the world of email.
