Internet certificate

Hello,

We implemented SSL few weeks back in our company. We have 3 r6.54 server and one r7 server.

Lately I am noticing that our users some times gets this message whenever they open an email.

“The internet service certificate is not trusted. Do you want to take corrective action now (i.e. retrieve service certificate and decide whether to trust it)?”

I understood that if some one sends an email using iNotes, it is happening. Is there a way to remove this message? Or What can be done to remove it?

Accidently during replication, all my address book of r6.5.4 got the design of R7 domino directory. Is that causing that message appearing? Is that a problem having a design of r7 template on r6.5.4 server?

Thanks in advance
