Outlook2K How2 import OpenSSL cert

Hi,

Ive asked this question multiple times on the MS newsgroups and looked on the MSKnowledgeBase and found nothing about importing certificates from a server using IMAP over SSL.

I have a RedHat7.2 box running sendmail/wu-imap/openssl w/ self signed certificate. It works fine. the line is encrypted. but everytime I check my mail this way OL2k/OLExpress warnes that the certificate cannot be verified. So I would like to import the certificate. How do I do so???
Are Digital ID's the same as certificates?

Any insight is appreciated.

thanx
