6c4663a045 Build the mail proxies and FTP only when they are asked for 
pop3p, imapp and smtpp are built with MAILPROXY=true, and ftppr and the
ftp:// scheme of the HTTP proxy with FTP=true; with CMake the switches are
3PROXY_USE_MAILPROXY and 3PROXY_USE_FTP. Neither is in a default build, and
the standalone binaries follow what was built.

A configuration naming one of them is still read either way. The three mail
protocols amount to a STARTTLS negotiation now that mail is carried over
TLS, so without a proxy of their own those names are tlspr speaking the
protocol: the file holds a stand-in which sets the protocol for the
connection and returns tlspr for the caller to run, which serves the
service name and a parent chain alike and leaves conf.c and the redirect
table untouched. FTP has no such fallback, so the service is known, answers
nothing and logs the refusal.

The Linux workflow builds both, so all of it is still compiled and run.

013d4bc333 tlspr (SNI proxy) implemented 
Options -cN - level of TLS check
default - allow non-TLS traffic
1 - require TLS, only check client HELLO packet
2 - require TLS, check both client and server HELLO
3 - require TLS, check server send certificate (not compatible with TLS 1.3)
4 - require mutual TLS, check server send certificate request and client sends certificate (not compatible with TLS 1.3)
-P - default port

examples:

1.
tlspr -p1443 -P443 -c1
(port 1443 may be used to redirect traffic to destination port 143). SNI is used to find destination host

2.
allow * * * 80
parent 1000 http 0.0.0.0 0
allow * * * * CONNECT
parent 1000 tls 0.0.0.0 0
deny * * some.not.allowed.host
allow *
socks

attempts to take destination hostname from SNI in SOCKS
