recently, my friend tried to register to my akkoma, but he didn't get any email anyway. Checked on my end via smtpctl show queue, but got no queue.

once i check the log, the mail server crashed because of two thing: – it can't connect to our postgresql db as it hasn't started yet – it can't bind to the smtp port

so, then i decided to modify the systemd service unit to make it always restart on every 10 seconds when theres a failure:

[Unit]
Description=OpenSMTPD SMTP server
Documentation=man:smtpd(8)
After=network.target

[Service]
Type=forking
ExecStart=/usr/sbin/smtpd

Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target

hopefully this doesn't happen again.
