While playing around with Exim 4.10 delivering messages to Cyrus, I
discovered that after negotiating TLS Exim issues a EHLO when it should
issue a LHLO. This is best demonstrated with the following debugging
snippet:
Connecting to localhost [127.0.0.1]:2003 ... connected

Philip, please consider the following patch for Exim 4.11. It is also
