Hi All,

I am inquiring into if anyone has secured their IMAP mail server so that your email client can connect securely when sending passwords to your server and so that you can download your mail encrypted instead of plain-text.

I have been successful in configuring my server to receive mail over SSL.  I cannot for the life of me get the 'Use secure authentication' checkbox in thunderbird email client working.

Here are my uname details:
Linux server.[].com 2.6.9-42.0.10.EL #1 Tue Feb 27 09:24:42 EST 2007 i686 i686 i386 GNU/Linux
OpenSSL 0.9.8k 25 Mar 2009
Courier-IMAP 3.0.8/i686-pc-linux-gnu/Tue Dec 18 20:54:31 NOVT 2007

I have created certs via mkimapdcert...

I need help with two things:
1) How do I configure server side secure authentication
2) How do I configure sending encrypted mail?


Here is the output when I try to test the sending of mail via SSL:

[root@server courier-imap]# openssl s_client -verify 0 -connect localhost:465
verify depth is 0
CONNECTED(00000003)
