What's New in This Release: [ read full changelog ]
· 2012-11-29 Enable basic DH support for STARTTLS in SMTP server.
· 2012-11-02 If a limit for outgoing connections was reached, the scheduler previously only tried other servers with the same MX preference (in contrast to actual temporary SMTP problems which would of course go through all available servers as specified in the RFCs). This behaviour was changed to try the next server even if it has a different MX preference in order to speed up delivery (the previous behaviour was implemented to avoid hitting "off site backup MX" servers which could make the overall deliver to the actual recipient longer, however, it seems very few sites actually still use those kind of setups).
