Problems with e-mail since account restore

Hello,


Recently I transfered a server to another datacenter due to price modifications. I backedup all accounts and restores them in the new server. Everything went ok, but the e-mail.

When I try to access via /webmail I can login with username and pw but when I open horde after choosing language I get a 404.

In Outlook it keeps saying that pw isn't right.
Tried to reinstall exim but afer the reinstall begun I got this error:

chown: cannot access `/etc/exim.crt': No such file or directory
chown: cannot access `/etc/exim.key': No such file or directory

Any help?

Thanks in advance for your time.
