Hi Stan, I'm sorry that my not clarifying the background of this unsettled you somewhat.
I'm a PhD student at the University of Antwerp <http://win.ua.ac.be/content/staff> and like many of my colleagues, I was dissatisfied with the webmail interface that the ICT would provide: It's old, it's buggy, and it seems unmaintained. Frustrating, but oh well, I guess that's how it goes sometimes. Anyway, some friends and I decided to have a look into free webmail solutions for us to use at the Computer Science department, and to play around with them a bit to see what's actually possible. This is purely a spare-time activity really, but the success in setting up RoundCube and getting a nice and modern webmail interface was quite satisfactory. Of course I don't demand official support for this in any way, but because of our performance problems I thought I'd just drop a line to the users' mailing list. Sorry if you felt startled by this. It's cool if you decide to ignore these mails of course, I mean, that's what people do with 99% of their mailing lists I guess. Anyway, thanks for your help so far. > You are posting here with a gmail address > instead of your university address. This is b/c the UA email doesn't perform well in some areas -- incredibly long delivery delays, 500MB mailbox limit, other funny things.
