TLS/SSL not working with some clients

[Mark Edwards]

I have imapd 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? I've seen reports via google searches of people having the issue using various clients, like some versions of Eudora, but I haven't found any claims of a solution.

Thanks!
