Secure e-mail certificate problems

[ManUtdFan]

I'm experiencing problems with a secure certificate on my Thinkpad X41 - I prefer to use Thunderbird but have also tried to use Outlook - both to no avail so far. I'm trying to set up my corporate e-mail account on my X41, and for incoming e-mails there's no problem at all. But to send outgoing e-mail, I need to go via our own secure SMTP server. The problem is that I never get the chance to obtain the certificate I need (TLS secured connection). I've tried to do it on several other computers, and it works fine every time. That leads me to suspect that some Thinkpad-specific software might be preventing me from obtaining such a certificate.

Perhaps you guys have some clues? Of course please ask for any more information you need!

There is no ThinkPad software I know of that would inhibit using any given SMTP server. I use several SMTP servers (about 5 in all) with Outlook 2003 and don't have any issue. I don't use the IBM security chip.

Are you doing this through a VPN? Have you configured your firewall to permit access?

I'm not using any kind of VPN or firewall... And I don't think that it's the SMTP server itself that's the problem - perhaps the certificate I have to install in order to use it? The problem it that I am never prompted to accept any certificate, which should happen automatically and has done so on every other computer I've used.
