Finally, I can get an email notification when clients' hard drives are too full. Or at least have something pop up in the client's face telling them something is wrong! Plus it's great not to have to pull down a menu to see what the situation is--the space is right there in the menubar.

Since I started using Space Control, nobody's drive has filled up, so I don't feel qualified to rate Quality/Stability. But I like it so far.

Only caveat is: when configuring for smtp, my password is saved in the clear. Not good. So it severely limits what systems I can set this up on at the moment (just desktops that don't travel, so the smtp server can be the ISP.) I would really really like this one thing to be fixed.

I would also like to be able to get notifications on non-boot drives. This would be useful for backups that need pruning occasionally. Carbon Copy Cloner, which I like, does not do email notifications on failure, such as one caused by No Space Left On Device.

Another suggestion: It's helpful that the setup includes suggestions for minimum free space, which, traditionally, have been 10-20% of the drive capacity. However, a recent macintouch.com discussion proposed 10x your RAM (has to do with swap space, I think), and more if you use something like Photoshop that needs scratch. Perhaps the suggestions could be updated, if this RAM angle is accurate.

Thanks for a very useful utility!
