DB 2.0 SUphp Problem (500 Internal Server Error)

[nade]

Hello,
I have done a fresh DA installation, on an debian 7.8 64 bit vps.

Everything looks good but two things annoy me a bit..

1. I need 2 php versions, php 5.3 and 5.5
I set it up like:

./build set mod_ruid2 no
./build set php1_release 5.5
./build set php2_release 5.3
./build set php1_mode suphp
./build set php2_mode suphp

Now i have the problem, that suphp wont let me run php files. i everytimes get internal error and the message "Directory /home is not owned by myuser"
I Searched in some forum´s and tryt to change the owner to root with

chown root:root /

but then php wont work on the host, when i try to set the permissions with ./set_permissions all, the internal 500 is back again..

Please give me a hint..

2.nd problem, is that i cant recieve mails, i can send mails. but i wont recieve them.. any ideas?

Thankyou

Provide a valid domain name where you cant get your email so we can check it, otherwise no that much help can be given.
