I was thinking of adding libsocks library calls for inbound or outbound remote SMTP connections. If I'm not mistaken, socksify etc. want to intercept not only TCP but also DNS. Would that work with DNSSEC? > I don't know if LD_PRELOAD is inherited by child processes spawned by Postfix. That is enabled with import_environment and export_environment https://www.postfix.org/postconf.5.html#import_environment https://www.postfix.org/postconf.5.html#export_environment You can filter or override environment settings.
