[mpop-users] Connecting to pop3 server fails with 'unknown protocol' error by SSL routine

[Edwin van der Horst <edwinvdh@...3...>]

Hello,

I have cross-compiled mpop to run on an Marvell XScale ARM9 platform.
with limited busybox fs
When I try to connect to the GMail POP server it mpop returns with a
unknown protocol header.
I'm lost at this point...
Does anyone have a clue what's going wrong here?
Thanks
