Re: version 2.5.2 bug?

It appears that my zebedee "persistent" reverse tunnel works okay if I do
NOT run the server as a WinXP service or detach from console.

If I do NOT have a console window, I can only send ONE e-mail through the
tunnel.

I see in the mail list archive that this is a known problem in 2.5.1 that
apparently was not fixed in 2.5.2:

 It looks like you've got a geniune bug there. There's currently no way to
 run it in "reverse" as a service (although that would have otherwise been a
 good way to get it to restart once the connecttimeout had expired). I'll
fix
 it in the next release.
