Hi group,

Is it possible to use TLS/SSL POP3 when the mail is being proxied via 
SpamBayes?

I'm using the 1.1b2 version of sb_server on Windows 10 with Thunderbird 
as the mail client.  I've configured SpamBayes to listen on port 53100, 
proxying to my mail provider.

When pointing Thunderbird to localhost:53100 without any security set, 
in combination with SpamBayes proxying to port 110 at my mail provider, 
everything works OK.

When pointing Thunderbird directly to my mail provider on port 995 with 
TLS/SSL checked, it can connect fine.

When in turn pointing Thunderbird to localhost:53100 with TLS/SSL 
checked, in combination with SpamBayes proxying to the same mail 
provider settings used above, fetching mails results in a time out after 
30 seconds in Thunderbird.

Updating the SpamBayes advanced setting "Retrieval timeout" from it's 
default of 30 seconds to 15 seconds didn't make a difference 
(Thunderbird still times out after 30 seconds), so it's not directly 
related to that I assume.

Looking if Thunderbird attaches anything significant to the port used 
(here 53100), I configured SpamBayes and Thunderbird to use the default 
port 995, but that made no difference either.

I've shut down both the SpamBayes server and Thunderbird between 
applying changes as well, but that didn't magically solve anything.

Is TLS/SSL supported by the SpamBayes proxy?

Thanks in advance!
