I/O error in SSL.

My round tuit finally arrived so I am trying to build 4.0.8 with TLS/SSL 
support.  I have it build successfully and tested it on my test system.  
So I moved it to the production system and just started the port 995 
version.  If SSL is enabled (-l 2) then I get

I/O Error
Error writing to client

when attempting to download any messages.  If I turn off SSL (no -l) 
then messages download successfully.

Anyone have any ideas on the problem?

incoming mail port 110 and 25?

Hi, Im new to qpopper.  Im running 4.0.8 on a fedora 3 box.
After figuring most things out I think I have it working,
to the extent that when I email from my off-site ISP to my
fedora box, the incoming email seems to hit port 25, not
110 (as I have it configured to do via xinetd etc).

I thought 110 was the 'standard' pop port?  Can someone
explain this or point me to some docs?

Thanks,
Jeff

Incoming mail goes to port 25.  Mail destined to go to a MAIL CLIENT 
goes out port 110.  Port 25: server, Port 110 Client.

When you send mail to the machine on which your POP3 server is running it 
is the SMTP server software on port 25 that receives it, not the POP3 
server on port 110.  The POP3 server on port 110 is only responsible for 
taking mail from the mail spool and uploading it to a POP3 client on your 
PC (or whatever).  It doesn't receive mail from POP3 clients or from other 
mail servers, nor does it deliver mail to other mail servers.  That is the 
responsibility of the SMTP server on port 25.

Thanks for all the help.  I get whats going on now. :)

As it turns out I really dont even need qpopper.
Im just going to forward messages via postfix's
virtual_alias table instead.

Thanks again!
