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.
The OpenSSL, wolfSSL, PCRE2 and PAM probes built their test program with
echo "...\n...". make runs recipes through /bin/sh, which is dash on Debian
and Ubuntu, where the builtin echo expands \n. On distributions where /bin/sh
is bash - every RPM based distribution, and macOS - it does not, so the probe
compiled
#include <openssl/ssl.h>n int main(){return 0;}
which is not valid C. Every probe therefore failed and the build silently
dropped TLS, PCRE2 and PAM support with no diagnostic.
Use printf, which expands escapes the same way everywhere.
! avoid errno usage due to compatibility issues (and never use errno as
a lvalue). socks changed to use internal error codes instead.
! NOIPV6 compilation issues solved
! -lite version is switched to NOIPV6
