The iPhone is simply picking up the fact that the certificate is not in the name of nildram but in the name of apm-internet.net that is authorised to host the nildram.co.uk domain. The iPhone is just being cautious but it is ok to trust this certificate.
There are two fixes.
During the add account process you'll have the opportunity to trust the server certificate when the settings are verified.
