[SM-DEVEL] TLS/SSL not working with some clients

[Mark E. <ma...@an...>]

I have UW-imap running on a FreeBSD 4.7 box, compiled via the ports tree 
with SSL support (this is the default).

I'm getting the following errors in /var/log/maillog when connecting 
with Squirrelmail 1.4.0 RC2a:

Feb 19 16:40:41 lilbuddy imapd[84173]: Unable to accept SSL connection, 
host=localhost [127.0.0.1]
Feb 19 16:40:41 lilbuddy imapd[84173]: SSL error status: 
error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

I can connect with SSL on port 993 from Mail.app (OSX), Outlook Express, 
and Mozilla mail just fine.  Something is causing a problem when 
connecting with Squirrelmail.  It appears to be an OpenSSL failure, but 
has anyone seen this or does anyone know how to fix it?

If I connect on port 143 it works, but it doesn't use SSL in that case.  
If I compile uw-imap normally (without plaintext authentication) then I 
can't connect via 143 at all, and if I connect on 993, I get the above 
messages.

Thanks!
