Backup location and maximum age can now be configured in the admin panel.
For now only S3 is supported, but adding other duplicity supported backends should be straightforward.
Some users report munin is broken because munin and munin-node disagree about the name of the machine. I think this occurs if hostname (used by munin-node) reports a different name than PRIMARY_HOSTNAME (which we put in the munin config).
Hard-code PRIMARY_HOSTNAME in munin-node.conf.
Fixes#474.
See https://discourse.mailinabox.email/t/404-not-found-on-admin-munin/623/24.
This is an extension of #427. Building on that change it adds support in the
aliases table for flagging aliases as:
1. Applicable to inbound and outbound mail.
2. Applicable to inbound mail only.
3. Applicable to outbound mail only.
4. Disabled.
The aliases UI is also updated to allow administrators to set the direction of
each alias.
Using this extra information, the sqlite queries executed by Postfix are
updated so only the relevant alias types are checked.
The goal and result of this change is that outbound-only catch-all aliases can
now be defined (in fact catch-all aliases of any type can be defined).
This allow us to continue supporting relaying as described at
https://mailinabox.email/advanced-configuration.html#relay
without requiring that administrators either create regular aliases for each
outbound *relay* address, or that they create a catch-all alias and then face a
flood of spam.
I have tested the code as it is in this commit and fixed every issue I found,
so in that regard the change is complete. However I see room for improvement
in terms of updating terminology to make the UI etc. easier to understand.
I'll make those changes as subsequent commits so that this tested checkpoint is
not lost, but also so they can be rejected independently of the actual change
if not wanted.

everything was already on master
While not widely supported, there are some browser addons that can
validate DNSSEC and TLSA for additional out-of-band verification of
certificates when browsing the web. Costs nothing to implement and
might improve security in some situations.
Recidive can be thought of as FAIL2BAN checking itself. This setup will monitor the FAIL2BAN log and if 10 bans are seen within one day activate a week long ban and email the mail in a box admin that it has been applied . These bans survive FAIL2BAN service restarts so are much stronger which obviously means we need to be careful with them.
Our current settings are relatively safe and definitely not easy to trigger by mistake e.g to activate a recidive IP jail by failed SSH logins a user would have to fail logging into SSH 6 times in 10 minutes, get banned, wait for the ban to expire and then repeat this process 9 further times within a 24 hour period.
The default maxretry of 5 is much saner but that can be applied once users are happy with this jail. I have been running a stronger version of this for months and it does a very good job of ejecting persistent abusers.
Explicitly set the timings and counts for the dovecot jail rather than change the global [DEFAULT] and inherit it for this one jail. These settings are far too safe so a future PR should increase security here.
Reverts the remaining FAIL2BAN settings to default: findtime 600 and maxretry 3. As jail settings override default settings this was hardly being used anyway so it is better to explicitly set it per jail as and when required.
--------------------
This is a minor update to v0.11, which was a major update. Please read v0.11's advisories.
* The administrator@ alias was incorrectly created starting with v0.11. If your first install was v0.11, check that the administrator@ alias forwards mail to you.
* Intrusion detection rules (fail2ban) are relaxed (i.e. less is blocked).
* SSL certificates could not be installed for the new automatic 'www.' redirect domains.
* PHP's default character encoding is changed from no default to UTF8. The effect of this change is unclear but should prevent possible future text conversion issues.
* User-installed SSL private keys in the BEGIN PRIVATE KEY format were not accepted.
* SSL certificates with SAN domains with IDNA encoding were broken in v0.11.
* Some IDNA functionality was using IDNA 2003 rather than IDNA 2008.
Modify outgoing_mail_header_filters and mail-postfix.sh
files to result in the primary hostname, and the public
ip of the server showing in the first mail header route
instead of unknown and 127.0.0.1. This could help lower
the spam score of mail sent from your server to some
public mail services.
Ban time was too low for preventing ssh brute force attacks, this change also allows to keep the auth.log more clean and avoid wasting cpu and i/o on this.
Bots eventually will flag your IP as secure and move along.
