I found three.
netcat-openbsd, netcat-traditional, netcat6.
netcat-openbsd pleads ignorance.
peter@dalton:~$ nc -l 25 -e ssmtp
nc: invalid option -- 'e'
...
netcat-traditional listens on the port; or appears to and does nothing.
peter@dalton:~$ nc -l 25 -e ssmtp
[gears humming]
netcat6 refuses.
peter@dalton:~$ nc -l -p 25 -e ssmtp

The browser doesn't have a means to include References in the header.
Sorry. References are at the top of the message and I can include
References in the header when mail is working again. More explanation here.

[Binding to a port below 1024] just requires that the process has the
CAP_NET_BIND_SERVICE capability.
Thanks. With that tip I might make nc in netcat6 work.
