Some help from FreeBSD Admins

[GunnCat]

Howdy.
We were compromised badly this last week and our sites have been offline for 3 days so far. We are in the process of straightening things up right now. We have moved from Debian to FReeBSD, but we're not sure about what software would be appropriate for us to use. I asked my partner write this:

Ok. Tell simply that we need an email solution (POP3+SMTP) that supports multiple domains AND the users can be administered over the web.
And tell that we need an FTP server which is able to change the owner of the uploaded files so that multiple users can edit them easily without running into permission problems. And which also has a webadmin for the users and homedirs. mention that we need the web admin for the administering the email accounts on the different domains.

If anyone has any sugesstions please feel free to list them because Marcell is new to FreeBSD.
Best,
GunnCat
