I have been using filesystem quotas for this purpose, and it works just fine. Off course, I have a "dedicated" filesystem for mail storage. > > Wietse > >> 2- there is no safe quota support in any MTA. most quota implementations >> will send a bounce, which may resultin backscatter true. but quotas are necessary: the more disk space the users have, the more garbage they store. >> 3- if you can queue mail, you can deliver it ;-p >> 4- disks don't cost too much now. true, but when you have >10k users, the cost of each "not so expensive" hard drive starts to add, and not only that, in a public organization you can have wait-times of around 6 months just to get a hard drive. Oh, and don't forget: you have plug these hard drives somewhere: every server has they "hard drives limit", and you could take a PC and lots of SATA controllers, and build a nice low-cost NAS-like thing, but a few people qualify this as "unreliable", they need to spend lots of money on IBM or HP storage systems, and because of the cost, they just don't buy them, and thus: we have a limited amount of disk space :( . >> 5- if your users abuse mail, destroy their heads, not ours. mmmm........ I don't think my boss let me do that, jejejeje :D c-ya! Ildefonso.
