IMAP handshake change

IMAP login didn't work.

I'm using Zoho Email.

It has the same problem as with GMail.

I changed this file:

sites/all/modules/civicrm/packages/ezc/Mail/src/transports/imap/imap_transport.php

In the method 'authenticate' I changed these lines:

//if ( $this->serverType === self::SERVER_GIMAP && strpos( $response, "* CAPABILITY" ) === 0 )
//

{ // $response = trim( $this->connection->getLine() ); // }

if ( strpos( $response, "* CAPABILITY" ) === 0 )

{ $response = trim( $this->connection->getLine() ); }

Now it works like a charm.

You may want to add another constant for Zoho like self::SERVER_GIMAP, or to find a more general solution.
