I don't get where people get these ideas. Queuing messages to the local
SMTP server as is done in PHP for Windows, is the slowest way to queue
messages because it requires a TCP connection where each address has to
be accepted individually by the SMTP server.
This is very slow when compared with direct injection of messages in the
mail queue which is what Unix MTAs do.
There seems to be better ways to queue messages under Windows than just
send them to the local SMTP server.
