Find out network card / port speed in FreeBSD

Under FreeBSD the ifconfig utility is used to assign an address to a network interface and/or configure network interface parameters.

The ifconfig utility must be used at boot time to define the network address of each interface present on a machine; it may also be used at a later time to redefine an interface’s address or other operating parameters.

Add greylisting to a FreeBSD Postfix Mail Server (howto)

Greylisting is an important tool in the war against spam.  Servers who connect to a mail server with an active greylisting are given a 450 recipent address rejected error the first time they try to connect and will not be allowed to successfully connect for a predefined time frame (normally a couple of minutes). A 450 SMTP error is not a permanent error and an RFC compliant mail server will try and resend the email again a bit later on. On the other hand the tools spammers tend to use do not adhere to standards and will not bother to retry sending the message again.
