You should not use port 25 for sending mails.
For authenticated users use submission port 587 with STARTTLS.
If you use port 25 you can not use things like postscreen (highly
effective keeping spam bots out) and other stuff will cause headache and
a hell of exemptions.

Which user is owning the files?

I am very satisfied with roundcube http://roundcube.net/
Running is instead with mod_php as user apache with mod_fcgi as a
separate user and basedir restrictions is not only improving security it
is also eliminating access rights problems.
