Welcome to plan9! > Where should i copy it. Glenda don't have permissions in this directory.
You need to add glenda to the group sys and upas, though ideally you really want to create a new username for yourself and add sys ane upas to this. Once you have done this you can edit the files in /mail/lib like /mail/lib/rewrite.gateway. You will probably also want to edit /mail/lib/remotemail. -Steve
