I'm using an older laptop now that has Thunderbird installed. When I
powered up the program this morning, Thunderbird updated to the most

have a "invalid certificate" or "same certificate" and rejects the
email from being sent.

I've spent the last hour trying to figure it out, but I can't find any
information on this. I never needed it before, now I do. It's the
same server I've used for years. The other odd thing is that my main
computer upgraded T-bird fine with no problems.

Any hints?

I'm using the portable because I'm officially crippled - seriously.
Short term, but crippled. :)

I'd appreciate any thoughts on it.


Are you trying to use SSL for your email? That might be the problem if
it is not supported on your server. Are you using the right port (110)
for incoming and 25 or 26 for outgoing?
