The problem is that you can't plan for a user receiving a 28MB email, or maybe 10 users getting a 28MB email!! Having the mail spool on the /var partition was probably OK in the days of small text only emails but attachments make it impossible to plan any kind of mail queue disk usage. The safest thing is to put it on a partition with the largest amount of free disk space. regards damian -- * Damian Hamill M.D. damian@cablenet.net * CableNet & The Landscape Channel * http://www.cablenet.net/ http://www.landscapetv.com/
