I used a config like this for testing:
```
global
log stdout format raw local0 debug
defaults
timeout connect 10s
timeout client 30s
timeout server 30s
log global
listen outboundsmtp
log global
bind 0:2526 accept-proxy
mode tcp
use-server v4 if { src 0.0.0.0/0 }
use-server v6 if { src ::/0 }
server v4 0.0.0.0 source 0.0.0.0 usesrc clientip
server v6 ::: source ::: usesrc clientip
```
Launched via:
```console
$ sudo haproxy -f assets/haproxy.conf -V
```
with the source:
```lua
kumo.define_egress_source {
name = 'w00t',
ha_proxy_server = '127.0.0.1:2526',
ha_proxy_source_address = '192.168.1.92',
}
```
refs: #19
Give the `main` page a non-empty title in the TOC.
The intent is that we'll roll that page over to a release specific
page when we cut a release and then empty out `main` again.
Enable the magiclink extension for mkdocs, so that GH issue number
links work without any additional ceremony.
