function SmtpTransport::setLocalDomain

Sets the name of the local domain that will be used in HELO.

This should be a fully-qualified domain name and should be truly the domain you're using.

If your server does not have a domain name, use the IP address. This will automatically be wrapped in square brackets as described in RFC 5321, section 4.1.3.
