Hi, I would like to filter some of my mail server-side so that I don't receive the postmaster copy of "undelievered" messages for some of my domain names. I've added the following rule to emmajane's account, but it doesn't seem to be /dev/nulling the email. :0B: * .*@xtrinsic.com.*: unknown user: /dev/null Any suggestions would be appreciated! -- Emma Jane Hogbin [[ 416 417 2868 ][ www.xtrinsic.com ]]
