8 # Mar 02 12:44:26 kw systemd[1]: This usually indicates unclean termination of a previous run, or service implementation deficiencies.
10 # 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.
11 # todo: consider hardening cups listening on 0.0.0.0
12 # todo: stop/disable local apache, and rpc.mountd, and kdeconnect when not in use.
13 # todo: check that spamd and unbound only listen locally.
15 # todo: hosts should only allow external mail that is authed and
16 # destined for backup route. it is a minor issue since traffic is
17 # limited to the wghole network.
19 # todo: emailing info@amnimal.ninja produces a bounce, user doesn't exist
20 # instead of a simple rejection like it should.
22 # todo: run mailping test after running, or otherwise
23 # clear out terminal alert
25 # todo: reinstall bk with bigger filesystem
27 # todo: on bk, dont send email if mailvpn is not up
29 # todo: mailtest-check should check on bk too
31 # todo: disable postgrey
33 # todo: in testforward-check, we should also look
35 # todo: test that bounces dont help create valid mailtest-check
37 # todo: move mail stuff in distro-end into this file
39 # todo: consider rotating dkim & publishing key so every past email I sent
40 # isnt necessarily signed
42 # todo: consider how to get clamav out of Debian-exim group
43 # so it cant read/write the whole mail spool, for better
46 # todo: create a cronjob to update or warn on expiring dnssec keys
48 # todo: we should test failed mail daily or so
49 # failed cronjob, failed sysd-log-once,
50 # a local bounce from a cronjob, a local bounce
51 # to a bad remote address, perhaps a local failure
52 # when the sending daemon is down.
53 # And send an alert email if no alerts have been sent
54 # in 2 or 3 days or something. todo, test cron mail on li.
56 # todo: look at mailinabox extra dns records, note these changelogs:
57 # - 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.
58 # - 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.
61 # todo: mailtest-check failure on remote hosts is not going to alert me.
63 # todo: test mail failure as well as success.
65 # todo: validate that mailtest-check is doing dnsbl checks.
67 # background: I want to run exim in a network namespace so it can send
68 # and receive through a vpn. This is needed so it can do ipv6, because
69 # outside the namespace if we dont have ipv6, to send ipv6 through the
70 # vpn, we have to send all our ipv6 through the vpn. I did this for a
71 # long time, it was fine, but it causes various pains, like increased
72 # latency, increased recaptcha because my ip is from a data center, just
73 # various issues I dont want on all the time. The problem with the
74 # namespace is that all kinds of programs want to invoke exim, but they
75 # wont be in the namespace. I could replace exim with a wrapper that
76 # jumps into the namespace, i tried that, it works fine. One remaining
77 # problem was that I would have needed to hook into exim upgrades to
78 # move exim and replace it with my wrapper script. Also, my script to
79 # join the namespace is not super reliable because it uses a pgrep.
80 # Instead, I should have created a systemd service for a process that
81 # will never die and just writes its pid somewhere convenient.
86 # user ALL=(ALL) /usr/sbin/exim4
88 # move exim4 to eximian, use this script for exim4:
91 # if ip a show veth1-mail &>/dev/null; then
92 # /usr/sbin/eximian "$@"
96 # if [[ $USER && $USER != root ]]; then
99 # pid=$(pgrep -f "/usr/sbin/openvpn .* --config /etc/openvpn/.*mail.conf")
101 # sudo nsenter -t $pid -n -m sudo -u $USER /usr/sbin/eximian "$@"
103 # nsenter -t $pid -n -m /usr/sbin/eximian "$@"
107 # an alternate solution: there is a small setguid program for
108 # network namespaces in my bookmarks.
110 # However, the solution I went with is: have 2 exim
111 # configs. A nonstandard location for the daemon that runs
112 # in the namespace. For all other invocations, it uses
113 # the default config location, which is altered to be
114 # in a smarthost config which sends mail to the deaemon.
116 # I have a bash function, enn to invoke exim like the daemon is running.
117 # and mailbash to just enter its network namespace.

679 # sooo, there are a few ways to get traffic from the mail network
680 # namespace to go over the wghole.
682 #1: unify the mail vpn and wghole
683 # into 1 network. this seems simple and logical, so I'm doing it.
684 # One general downside is tying things together, if I need to mess
685 # with one thing, it breaks the other. Oh well for now.
687 # 2. We can route 10.5.3.0/24 out of the mail nn and nat it into wghole.
689 # 3. We can setup the routing to happen on li, which seemed like I
690 # just needed to add 10.8.0.4/24 to AllowedIPs in at least the
691 # wghole clients, but I think that is kind of hacky and breaks ipv4
692 # routing within the mailvpn, it happened to work just because exim
693 # prefers ipv6 and that was also available in the mailvpn.
695 # 4. Put the hole interface into the mail network namespace. This
696 # doesn't work if the mail vpn is wg. For openvpn, it bypasses the
697 # vpn routing and establishes a direct connection. I only use the
698 # hole vpn for randomish things, it should be fine to join the mail
699 # nn for that. There should be some way to fix the routing issue
700 # by doing manual routing, but that doesn't seem like a good use of time.

3183 # /etc/alias setup is debian specific, and exim postinst script sets up

3185 # exim4-config exim4/dc_postmaster, as long as there exists an entry for
3186 # root, or there was no preexisting aliases file. postfix won\'t set up
3187 # a root to $postmaster alias if it\'s already installed. Easiest to
3188 # just set it ourselves.
3190 # debconf question for postmaster:
3191 # Mail for the 'postmaster', 'root', and other system accounts needs to be redirected
3192 # to the user account of the actual system administrator.
3193 # If this value is left empty, such mail will be saved in /var/mail/mail, which is not
3195 # Note that postmaster\'s mail should be read on the system to which it is directed,
3196 # rather than being forwarded elsewhere, so (at least one of) the users listed here
3197 # should not redirect their mail off this machine. A 'real-' prefix can be used to
3198 # force local delivery.
3199 # Multiple user names need to be separated by spaces.
3200 # Root and postmaster mail recipient:
3206 # eval: (outline-minor-mode)
3207 # outline-regexp: "\\( *\\)# [*]\\{1,8\\} "
3209 # this is combined with defining outline-level in init.el
