Description
The relay restrictions have been entirely reimagined to feature a more user-friendly interface that allows for enhanced control over relay security measures. Additionally, EIMS introduces its own Domain Name Resolver (DNR), designed to address issues present in the Open Transport DNR and to improve performance compared to the OS X DNR, although it currently lacks support for non-recursive DNS configurations. Furthermore, a new SMTP Submit port has been added, operating on TCP port 587 by default, mirroring the functionality of the standard SMTP port; this is particularly beneficial for clients whose ISPs restrict access to port 25. An option to set a maximum number of recipients per message has been incorporated, and the previously mandatory Expand SMTP Addresses feature can now be disabled, a change from EIMS versions 3.1 and earlier where it was always enabled. In addition, the SMTP server on both ports 25 and 587 is now equipped to log Telnet connections and recognize activities resembling port scans, enhancing security monitoring capabilities. Overall, these updates aim to provide users with greater flexibility and security when managing their email services.
