Log Message:
Include a patch taken from the main Courier CVS repository that adds
a new TLS_PROTOCOL selection "SSL23" that allows for trying to negotiate
initially with SSLv3 but falling back to SSLv2:

	courier/tcpd/libcouriertls.c:1.21

This allows Courier to interoperate with older mail servers and clients
that are still using SSLv2 when advertising or attempting to use
advertised STARTTLS capabilities.

This change modifies the following packages and bumps their PKGREVISIONs:

	mail/courier-imap	to 1.
	mail/courier-mta	to 6.
	meta-pkgs/courier	to 2.
	net/couriertcpd		to 1.
