8.5.2 - Domino Web Access/iNotes Issues

We have two issues following an upgrade of a standalone Domino server to 8.5.2 from 8.5.1 FP4. No configuration changes have been made.

i) We used to be able to connect to the iNotes on the server using http://servername which would open a database called Open.nsf. We now have to specify http://servername/open.nsf

ii) When we reply to an internet e-mail via the iNotes client, @ourdomain is appended to the address, causing the server to attempt internal delivery which fails. If we type in th full address the mails are delivered fine.

Any help would be greatly appreciated.
