Socket with IMAP server troubles :)

[dekoffie]

Hello there,

I'm trying to create a connection with an IMAP server which is secured
through SSL. I can get the connection just fine, and I get a first respone
from the server. But then I send out my login string, and it does not seem
to arrive at the server, because I don't get an answer returned! After some
time, I receive a message from the server saying that I've been idle for too
long, and then the connection gets closed..
But why doesn't my data arrive at the server? (because I believe that 's the
problem here).

I realy hope someone could help me out :)
