performance boost?

[Simon K. Grabowski]

Hi,

Is there any speed/performance gain if I inject messages
directly via /mail/qmail/bin/qmail-inject instead of using
sendmail replacement (/mail/qmail/bin/sendmail)?
I know that sendmail command ultimately uses qmail-inject
to inject the messages so I figured I'd cut the 'middle-men'.

It appears that there are no side-effects provided that
I add "Return-Path <[EMAIL PROTECTED]>"
in the beginning of the message.

Can there be any problems with such a set up?

Thanks!
