I'm glad to know that. I'll have to take a look at it then.

It is dangerous to put any webmail application on a mailserver
for a couple reasons. First it is possible for users of the
app (assuming the app has the ability to save mail) to overflow
directories on the mailserver. However more seriously, any
www application is always subject to security issues - a hole in
the application, even if the apache version your using is secure -
allows spammers to relay through your mailserver. Mailservers are
of course, the most desired of spam relays.

I think OpenWebmail is probably equal or surpassing one of those.
In terms of features, OpenWebmail has all the other webmail apps
out there beaten - except for IMP, and possibly squirrelmail, but
I don't know enough about squirrelmail to rate it.
In the last analysis, the most users will gravitate towards the
webmail app that has the most features.
