It encompasses all essential features at a reasonable price, helping to avoid typical issues tied to email servers.

With competitive licensing charges, the absence of server client access licenses (CALs), and dependable performance, it stands out as a preferred option for small to medium-sized businesses and home offices alike. Effective email communication is vital for any organization, making the security of stored messages crucial for ongoing success. While operating your own email server may come with certain complexities and costs, it allows full physical control over who can access your email correspondence. In comparison, using an email service provided by your internet service provider raises significant privacy issues, as their personnel could potentially read your private messages. Similarly, relying on a software-as-a-service (SaaS) provider for hosted email solutions can leave you in the dark regarding who has access to your emails and the actual location of your data storage. Thus, choosing Mailtraq not only grants you control but also provides reassurance regarding the integrity and confidentiality of your email communications. This level of security and oversight is particularly beneficial for organizations that prioritize data protection and wish to maintain a clear understanding of their email environment.

    The restrictions on relay functionality have been completely revamped to include a more intuitive interface that enhances user control over security protocols associated with relays. In addition, EIMS has introduced a proprietary Domain Name Resolver (DNR) that aims to rectify the shortcomings of the Open Transport DNR and offers better performance than the OS X DNR, although it does not yet support non-recursive DNS configurations. A new feature has been added with the inclusion of an SMTP Submit port, which operates by default on TCP port 587, effectively replicating the capabilities of the traditional SMTP port and proving especially advantageous for users whose internet service providers impose limitations on port 25. Users can now set a cap on the number of recipients allowed per email, and the previously compulsory Expand SMTP Addresses feature can now be turned off, marking a significant shift from EIMS versions 3.1 and earlier where it could not be disabled. Moreover, the SMTP server on both ports 25 and 587 is now capable of logging Telnet connections and identifying behaviors similar to port scanning, which significantly bolsters security monitoring functions. Overall, these enhancements are designed to empower users with improved flexibility and security in their email management, thus adapting to contemporary needs. This comprehensive update reflects a commitment to evolving user demands and technological advancements in email services.
