Hello,

Any ideas??

This is the only errors i can find .

Please help!
 
I see only 'fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit' and it is indicate that Postfix is not correctly configured there.

Check that you have default value there:

# rpm -ql postfix | grep main.cf
/etc/postfix/main.cf
/etc/postfix/main.cf.default
# grep size_limit /etc/postfix/main.cf
message_size_limit = 1048576
