[imp] Server does not support TLS connections

Hello,

as of today we have the problem that after working for some time  
Horde/IMP suddenly log "Server does not support TLS connections" for  
connections to the IMAP server, which is obviously false because it  
worked before and the IMAP server does indeed advertise and use TLS  
like this:

* OK [CAPABILITY IMAP4rev1 LITERAL+ ID ENABLE STARTTLS AUTH=PLAIN  
AUTH=LOGIN SASL-IR] mailer Cyrus IMAP v2.4.17-Debian-2.4.17-1ubuntu1  
server ready\x0d\x0a

but the connection from the webserver is always closed (FIN,ACK) after this.

Horde/IMP then tries with around 20/s to connect to the IMAP server  
constantly blasting the log with

Aug 13 12:48:09 ftp HORDE: [imp] Der E-Mail-Server unterstützt keine  
TLS-Verbindungen. [pid 6226 on line 94 of  
"/var/www/horde/imp/lib/Imap/Exception.php"]
Aug 13 12:48:09 ftp HORDE: [horde] imp is not activated. [pid 6226 on  
line 1493 of "/usr/share/php/Horde/Registry.php"]
