Mailscanner, MTA and postfix questions

[James Sizemore]

I run in single instance Postfix mode as well. I also don't use MailWatch,
But have never seen double entries in the logs.  I run under a very high
volume of email as well.  Sendmail in not even an option for me as a
mail server with out the ability to "transport" is useless to me. <smile>
