exscuse me? so you're saying that if they can only access the webserver
(ie. port 80) no one could ever hack the box? if f.ex. one were to use a
package like IMP (and the 10 other projects that go along with it) -
there's a big chance that there's a security issue with one of them,
that might give shell access as the webserver user (normally nobody).
>From there on, it's often possible to use some local exploit - and in
the case of NFS/MAPI/SMB shares, that's not even necessary and it IS a
lot easier to find flaws in a NFS/MAPI/SMB service than in the
courier-imap service. So If I were a security minded Admin, I would
prefer to allow access to users Email via Imap - as it has the best
security record of the options available.
