I posted this message as a comment to the HOWTO I used to configure my mail server:
http://www.howtoforge.com/fedora_virtual_postfix_mysql_quota_courier
I've been running a mail server built using this HOWTO for a while now. I recently updated the entire server with a "yum update". Email clients could no longer connect to the server via POP3 or IMAP if SSL was enabled. I was getting errors like this in the error log:
Oct 23 13:19:32 mailhost pop3d-ssl: couriertls: connect: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
Oct 24 10:36:13 mailhost imapd-ssl: couriertls: connect: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
I was able to fix this by editing the following files:
/usr/lib/courier-imap/etc/imapd-ssl
/usr/lib/courier-imap/etc/pop3d-ssl
I changed the TLS_PROTOCOL setting from SSL3 to SSL23 in both of these files:
TLS_PROTOCOL=SSL23
Then, I restarted courier-authlib and courier-imap and things were working again:
service courier-authlib restart
service courier-imap restart
The following commands were helpful in testing things out:
openssl s_client -connect mailhost:993 -state -debug
openssl s_client -connect mailhost:995 -state -debug
openssl s_client -ssl2 -connect mailhost:993 -state -debug
openssl s_client -ssl3 -connect mailhost:993 -state -debug
openssl s_client -ssl2 -connect mailhost:995 -state -debug
openssl s_client -ssl3 -connect mailhost:995 -state -debug
I hope this helps someone else, as I spent way too much time trying to solve it.

Courier services are very useful services which helps to transport items or products of various sorts that might be required to be delivered urgently, safely or discreetly. The items that need to be couriered may be something valuable like- bank drafts, legal business documents, mail order items, films and tapes, artwork or fragile items like computer monitors. In fact there are special medical courier companies that transport medical supplies, blood samples, organs and so on. la courier
