How to install s/mime certificate in Ubuntu

I have installed 8.5 Beta 2 in Ubuntu Intrepid 8.10.

How do I install a thwate or comodo personal mail certificate in Lotus so I can use s/mime?

did you ever get an answer to your s/mime question? normally, you will import your digital certificate (x.509 support in some type of .pcks format from thwarte). Once you import the digital cert into notes, it will be present in your ID file and/or personal nab. thwarte should have provided some instruction on this as the CA provider.
