I'm testing advanced email filtering using a pass-through script to copy
email without actually changing the contents, but without success. The
email stays stuck in the queue. I am using a pipe that should respond
to port 10025. It does respond to telnet:
Telnet response from 10025:
$ telnet 127.0.0.1 10025
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
status0
Telnet response from 10026:
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
220 mail.privacy-computer.com ESMTP
