80 # 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.
81 # todo: consider hardening cups listening on 0.0.0.0
82 # todo: stop/disable local apache, and rpc.mountd, and kdeconnect when not in use.
84 # todo: hosts should only allow external mail that is authed and
85 # destined for backup route. it is a minor issue since traffic is
86 # limited to the wghole network.
88 # todo: emailing info@amnimal.ninja produces a bounce, user doesn't exist
89 # instead of a simple rejection like it should.
91 # todo: run mailping test after running, or otherwise
92 # clear out terminal alert
94 # todo: disable postgrey

103 # isnt necessarily signed
105 # todo: consider how to get clamav out of Debian-exim group
106 # so it cant read/write the whole mail spool, for better
109 # todo: create a cronjob to update or warn on expiring dnssec keys
111 # todo: we should test failed mail daily or so
112 # failed cronjob, failed sysd-log-once,
113 # a local bounce from a cronjob, a local bounce
114 # to a bad remote address, perhaps a local failure
115 # when the sending daemon is down.
116 # And send an alert email if no alerts have been sent
117 # in 2 or 3 days or something. todo, test cron mail on li.
119 # todo: look at mailinabox extra dns records, note these changelogs:
120 # - 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.
121 # - 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.
124 # todo: mailtest-check failure on remote hosts is not going to alert me.
126 # todo: test mail failure as well as success.
128 # todo: validate that mailtest-check is doing dnsbl checks.
130 # background: I want to run exim in a network namespace so it can send
131 # and receive through a vpn. This is needed so it can do ipv6, because
132 # outside the namespace if we dont have ipv6, to send ipv6 through the
133 # vpn, we have to send all our ipv6 through the vpn. I did this for a
134 # long time, it was fine, but it causes various pains, like increased
135 # latency, increased recaptcha because my ip is from a data center, just
136 # various issues I dont want on all the time. The problem with the
137 # namespace is that all kinds of programs want to invoke exim, but they
138 # wont be in the namespace. I could replace exim with a wrapper that
139 # jumps into the namespace, i tried that, it works fine. One remaining
140 # problem was that I would have needed to hook into exim upgrades to
141 # move exim and replace it with my wrapper script. Also, my script to
142 # join the namespace is not super reliable because it uses a pgrep.
143 # Instead, I should have created a systemd service for a process that
144 # will never die and just writes its pid somewhere convenient.
145 # That implementation
149 # user ALL=(ALL) /usr/sbin/exim4
151 # move exim4 to eximian, use this script for exim4:
154 # if ip a show veth1-mail &>/dev/null; then
155 # /usr/sbin/eximian "$@"
159 # if [[ $USER && $USER != root ]]; then
162 # pid=$(pgrep -f "/usr/sbin/openvpn .* --config /etc/openvpn/.*mail.conf")
164 # sudo nsenter -t $pid -n -m sudo -u $USER /usr/sbin/eximian "$@"
166 # nsenter -t $pid -n -m /usr/sbin/eximian "$@"
170 # an alternate solution: there is a small setguid program for
171 # network namespaces in my bookmarks.
173 # However, the solution I went with is: have 2 exim
174 # configs. A nonstandard location for the daemon that runs
175 # in the namespace. For all other invocations, it uses
176 # the default config location, which is altered to be
177 # in a smarthost config which sends mail to the deaemon.
179 # I have a bash function, enn to invoke exim like the daemon is running.
180 # and mailbash to just enter its network namespace.

803 # sooo, there are a few ways to get traffic from the mail network
804 # namespace to go over the wghole.
806 #1: unify the mail vpn and wghole
807 # into 1 network. this seems simple and logical, so I'm doing it.
808 # One general downside is tying things together, if I need to mess
809 # with one thing, it breaks the other. Oh well for now.
811 # 2. We can route 10.5.3.0/24 out of the mail nn and nat it into wghole.
813 # 3. We can setup the routing to happen on li, which seemed like I
814 # just needed to add 10.8.0.4/24 to AllowedIPs in at least the
815 # wghole clients, but I think that is kind of hacky and breaks ipv4
816 # routing within the mailvpn, it happened to work just because exim
817 # prefers ipv6 and that was also available in the mailvpn.
819 # 4. Put the hole interface into the mail network namespace. This
820 # doesn't work if the mail vpn is wg. For openvpn, it bypasses the
821 # vpn routing and establishes a direct connection. I only use the
822 # hole vpn for randomish things, it should be fine to join the mail
823 # nn for that. There should be some way to fix the routing issue
824 # by doing manual routing, but that doesn't seem like a good use of time.
