+To offer SMTP over TLS (submission port), we can no longer use /bin/service files, since

-First, create a file /rc/bin/service/tcp587:
+Instead, we will start upas/smtpd from cpustart, and call aux/listen with -t.
+cpu% mkdir /cfg/$sysname/service.upas
+cpu% cp /bin/service/!tcp587 /cfg/$sysname/service.upas/tcp587

+Then, we edit tcp587:

+cpu% cat tcp587
#!/bin/rc
user=`{cat /dev/user}-exec upas/smtpd -a -c /sys/lib/tls/acmed/example.com.crt -e -f -s -n $3

-Next, set the file to executable:

+Make sure to set the file as executable:
