If you specify mynetworks, mynetworks_style is ignored.

For example, specifying "mynetworks_style = subnet" indicates that all clients in that subnet are trusted, while mynetworks = 50.116.33.0/24 might be used instead to say the same thing (if 50.116.33.0/24 describes your subnet). These clients are "trusted" because the mynetworks (or mynetworks_style) parameter is used by smtpd to determine who is allowed to relay mail when the smtpd_relay_restrictions parameter contains "permit_mynetworks." If you haven't changed smtpd_relay_restrictions in your config, it defaults to "permit_mynetworks, reject_unauth_destination," which will allow those clients listed in mynetworks (or mynetworks_style) to relay mail. You only need to use mynetworks OR mynetworks_style (but not both) to enable relaying from certain clients. Read the documentation when you get confused. It is explained quite clearly here: http://www.postfix.org/postconf.5.html#mynetworks http://www.postfix.org/postconf.5.html#mynetworks_style http://www.postfix.org/postconf.5.html#smtpd_relay_restrictions -Will

I'm sure you'll find many things you like better than qmail, some maybe not so much. But I think you'll find an active support community with Postfix. The fact that the author himself still answers questions, daily, should tell you something about the level of support Postfix receives, unlike what happened to qmail. -- Stan

Problem: Recipient address rejected: User unknown in virtual mailbox table
I have Postfix/DoveCot/SASL with mysql setup up running on Ubuntu Server
10.04. I believe that when the mail comes in, something in the settings
is not allowing the data to be parsed correctly resulting in the User
unknown error.
Here is the output from postfinger

Le 14/12/2012 11:28, Muhammad Yousuf Khan a écrit : > Thanks :) > and it is recommended to use mynetworks. This is because mynetwork_style may open a hole in some situations (when your netwmaks is wide but you only own few boxes in the same network. this is generally the case for residential networks). you can generally start with mynetworks = 127.0.0.1 and then add the minimum subnets or IPs that need to relay via this postfix without SASL authentication.
