Configuring local_recipient_maps in main.cf
The local_recipient_maps parameter specifies lookup tables with all
names or addresses of local recipients. A recipient address is local
when its domain matches $mydestination, $inet_interfaces or
$proxy_interfaces. If a local username or address is not listed in
$local_recipient_maps, then the Postfix SMTP server will reject the
address with “User unknown in local recipient table”.

The default setting, shown below, assumes that you use the default
Postfix local(8) delivery agent for local delivery, where recipients
are either UNIX accounts or local aliases:

/etc/postfix/main.cf:
local_recipient_maps = proxy:unix:passwd.byname $alias_maps
To turn off unknown local recipient rejects by the SMTP server, specify:

/etc/postfix/main.cf:
local_recipient_maps =
That is, an empty value. With this setting, the Postfix SMTP server
will not reject mail with “User unknown in local recipient table”.

Sharepoint 2007 Unknown Error when deleting list columns

roadburn — Wed, 03 Dec 2008 07:46:38 +0000

Did you customize your application master pages and get this error while trying to delete list columns?

Unable to validate data. at System.Web.Configuration.MachineKeySection.GetDecodedData(Byte[] buf, Byte[] modifier, Int32 start, Int32 length, Int32& dataLength)

at System.Web.UI.ObjectStateFormatter.Deserialize(String inputString)

Ok that probably means you have a search box in the template which is messing things up, just remove it or hide it, and that will do the trick!
