Can someone please explain e-mail disc usage. When my disc space is used up does that mean it is no longer possible to use e-mail until some space is released?
This is true on any server where you have a limited quota of space. The solutions are simple: 1) get rid of the space holding tons of emails & attachments (can be done with gzip and offline storage or just delete) 2) get rid of files and directories (same as #1) 3) buy more diskspace. (get out your checkbook)
