I am having a problem using TLS with my SPAMCOP account. Using straight SSL on port 995 usually works OK. However, using TLS on port 110 is a hit or miss proposition. Here are two logs of my attempts to download mail using TLS.

I am using claws-mail on a FreeBSD-6.3 machine, although that should not make any difference. If it works one time, it should work all the time.

Hi, Gerard!
...Since it has been two days since you posted and there have been no replies, I would suggest you contact JT directly. Try e-mail contact form. IIUC, there's a link to the form on the webmail home page (but I can't verify that myself as I am not a SpamCop e-mail user).
...Good luck!

We have several machines in a load-balancing fault-tolerant system. It looks like STLS was not enabled on at least one machine. I've changed this and I think it should work across the system now.
