7 # todo: setup an alert for bouncing test emails.
9 # todo: bounces to my fsf mail can come from fsf@iankelling.org,
10 # think about making bounces go from the original address.
12 # todo: add a prometheus alert for dovecot.
14 # todo: handle errors like this:
15 # Mar 02 12:44:26 kw systemd[1]: exim4.service: Found left-over process 68210 (exim4) in control group while starting unit. Ignoring.
16 # Mar 02 12:44:26 kw systemd[1]: This usually indicates unclean termination of a previous run, or service implementation deficiencies.
18 # todo: harden dovecot. need to do some research. one way is for it to only listen on a wireguard vpn interface, so only clients that are on the vpn can access it.
19 # todo: consider hardening cups listening on 0.0.0.0
20 # todo: stop/disable local apache, and rpc.mountd, and kdeconnect when not in use.
22 # todo: hosts should only allow external mail that is authed and
23 # destined for backup route. it is a minor issue since traffic is
24 # limited to the wghole network.
26 # todo: emailing info@amnimal.ninja produces a bounce, user doesn't exist
27 # instead of a simple rejection like it should.
29 # todo: run mailping test after running, or otherwise
30 # clear out terminal alert
32 # todo: disable postgrey
34 # todo: in testforward-check, we should also look
36 # todo: test that bounces dont help create valid mailtest-check
38 # todo: move mail stuff in distro-end into this file
40 # todo: consider rotating dkim & publishing key so every past email I sent
41 # isnt necessarily signed
43 # todo: consider how to get clamav out of Debian-exim group
44 # so it cant read/write the whole mail spool, for better
47 # todo: create a cronjob to update or warn on expiring dnssec keys
49 # todo: we should test failed mail daily or so
50 # failed cronjob, failed sysd-log-once,
51 # a local bounce from a cronjob, a local bounce
52 # to a bad remote address, perhaps a local failure
53 # when the sending daemon is down.
54 # And send an alert email if no alerts have been sent
55 # in 2 or 3 days or something. todo, test cron mail on li.
57 # todo: look at mailinabox extra dns records, note these changelogs:
58 # - An MTA-STS policy for incoming mail is now published (in DNS and over HTTPS) when the primary hostname and email address domain both have a signed TLS certificate installed, allowing senders to know that an encrypted connection should be enforced.
59 # - The per-IP connection limit to the IMAP server has been doubled to allow more devices to connect at once, especially with multiple users behind a NAT.
62 # todo: mailtest-check failure on remote hosts is not going to alert me.
64 # todo: test mail failure as well as success.
66 # todo: validate that mailtest-check is doing dnsbl checks.
68 # background: I want to run exim in a network namespace so it can send
69 # and receive through a vpn. This is needed so it can do ipv6, because
70 # outside the namespace if we dont have ipv6, to send ipv6 through the
71 # vpn, we have to send all our ipv6 through the vpn. I did this for a
72 # long time, it was fine, but it causes various pains, like increased
73 # latency, increased recaptcha because my ip is from a data center, just
74 # various issues I dont want on all the time. The problem with the
75 # namespace is that all kinds of programs want to invoke exim, but they
76 # wont be in the namespace. I could replace exim with a wrapper that
77 # jumps into the namespace, i tried that, it works fine. One remaining
78 # problem was that I would have needed to hook into exim upgrades to
79 # move exim and replace it with my wrapper script. Also, my script to
80 # join the namespace is not super reliable because it uses a pgrep.
81 # Instead, I should have created a systemd service for a process that
82 # will never die and just writes its pid somewhere convenient.
87 # user ALL=(ALL) /usr/sbin/exim4
89 # move exim4 to eximian, use this script for exim4:
92 # if ip a show veth1-mail &>/dev/null; then
93 # /usr/sbin/eximian "$@"
97 # if [[ $USER && $USER != root ]]; then
100 # pid=$(pgrep -f "/usr/sbin/openvpn .* --config /etc/openvpn/.*mail.conf")
102 # sudo nsenter -t $pid -n -m sudo -u $USER /usr/sbin/eximian "$@"
104 # nsenter -t $pid -n -m /usr/sbin/eximian "$@"
108 # an alternate solution: there is a small setguid program for
109 # network namespaces in my bookmarks.
111 # However, the solution I went with is: have 2 exim
112 # configs. A nonstandard location for the daemon that runs
113 # in the namespace. For all other invocations, it uses
114 # the default config location, which is altered to be
115 # in a smarthost config which sends mail to the deaemon.
117 # I have a bash function, enn to invoke exim like the daemon is running.
118 # and mailbash to just enter its network namespace.

680 # its the same file so it does no harm.
687 # sooo, there are a few ways to get traffic from the mail network
688 # namespace to go over the wghole.
690 #1: unify the mail vpn and wghole
691 # into 1 network. this seems simple and logical, so I'm doing it.
692 # One general downside is tying things together, if I need to mess
693 # with one thing, it breaks the other. Oh well for now.
695 # 2. We can route 10.5.3.0/24 out of the mail nn and nat it into wghole.
697 # 3. We can setup the routing to happen on li, which seemed like I
698 # just needed to add 10.8.0.4/24 to AllowedIPs in at least the
699 # wghole clients, but I think that is kind of hacky and breaks ipv4
700 # routing within the mailvpn, it happened to work just because exim
701 # prefers ipv6 and that was also available in the mailvpn.
703 # 4. Put the hole interface into the mail network namespace. This
704 # doesn't work if the mail vpn is wg. For openvpn, it bypasses the
705 # vpn routing and establishes a direct connection. I only use the
706 # hole vpn for randomish things, it should be fine to join the mail
707 # nn for that. There should be some way to fix the routing issue
