Version 5.6 - Build 2145 (2014-11-13) - Production
Sometimes an error was logged when hMailServer received a message over SMTP (issue has not existed prior to 5.6)
The number of current TCP connections were not always counted properly (normally 2-3 extra connections were shown), leading to incorrect info on Status page. Issue occurred when you had multiple ports set up for same protocol.

Issue 50: Forwarding of message should update From-address to forwarding account address.

Added TCP/IP port 587 as new port for SMTP (affects new installations only)
Reverse DNS lookup now works for IPv6
Added support for DH ciphers for TLS. Enables Perfect Forward Secrecy.

Version 5.5.1 - Build 2076 (2014-09-22)
An unknown issue is causing hMailServer to stop responding. An attempt has been made to address this.
Message delivery failed if recipient server did not support EHLO.
Version 5.5 - Build 2074 (2014-09-04)
If an IP address is specified as Target SMTP Host for a SMTP Relayer or SMTP Route, hMailServer would always attempt to deliver to 127.0.0.1 and the delivery would fail.
An experimental fix has been made to an issue related to session counting. Previously, hMailServer could assume that the number of current sessions were higher than they actually were.
When communicating with other SMTP servers, hMailServer will now assume that they support ESMTP, even if they do not advertise that in the initial greeting. This solves an issue where hMailServer would not use STARTTLS even if the remote server supported it.
When communicating with MySQL, hMailServer will now use the utf8mb4 character set for the connection if MySQL supports it. Previously hMailServer as using the utf8 character set.
WebAdmin has been updated to use UTF-8, which means that entering for example a signature with Japanese characters now works.
Issue 18: If several attachments were blocked in the same email, hMailServer now adds the same number of new attachments describing that the original attachment was removed. Previously only one attachment was added.
Issue 21: The SMTP error code for "Recipient not in route list" has been changed from 421 to 550, to indicate that this is a permanent error.
Version 5.5 - Build 2058 (2014-08-15)

Version 5.4 - Build 1949 (2013-05-19)
hMailServer now consolidates outgoing email messages smarter when routes and SMTP relayer is in use. This results in fewer connections to the SMTP relay / route server.
Sometimes using SpamAssassin resulted in corrupt email messages due to incorrect parsing by SpamAssassin response.
Version 5.4 - Build 1948 (2013-05-05)
Sometimes files remained in temp directory after SpamAssassin had been invoked.
Version 5.4 - Build 1947 (2013-04-09)

Mailbox sometimes remained locked after a timeout.
All recipients to particular route kept combined instead of split into individual emails.
