Stargate has been cross-migrated to a new and faster hardware. In the same process, the OS has been updated and the software used to deliver mail changed from cyrus to dovecot. As a goodie, all security protocols have been enhanced again, and dynamic blacklisting is even more sensitive than it was before - as SMTP auth probing is now taken into account.
The hardware specs are as follow:

• CPU: Intel(R) Core(TM) i7-3770T CPU @ 2.50GHz
• 16GB Ram
• 1x60GB SSD for the OS
• 2x320GB HD @ 7200RPM configure as Raid 1

Note that there are no user accounts on that server available.
