The SMTP courier, which handles outgoing connections, uses the domain of the envelope's from as the domain in the HELO/EHLO greeting. This works fine in practice, but ideally the domain used in the greeting should match the reverse DNS record. This used to be more relevant but nowadays it is not really enforced; however, it sometimes comes up in self checks, and might cause some confusion when troubleshooting. So this patch makes it use the configured hostname instead, which is under the users' control and more likely to be compliant. It also simplifies the code. The documentation of the hostname configuration option is also updated to mention this behaviour. Thanks to Jonas Seydel (thor77) for bringing this up.
