Native Anti Hammer - Brute-force attack protection Proprietary with OSS parts, a community ( Freeware) and 3 paid editions (SMB, Enterprise, Hosting) Proprietary/ SaaS, with open-source parts Proprietary (free version: 5 domains, 5 users, 5 groups) Microsoft Windows servers do not natively implement e-mail, thus Windows-based MTAs have to supply all the necessary aspects of e-mail-related functionality.Įmbedded, Optimized for Email & Groupware Unix-based MTA software largely acts to enhance or replace the respective system's native MTA. Mail is read either through direct access ( shell login) or mailbox protocols like POP and IMAP. To allow the server to send external emails, an MTA such as Sendmail, Postfix, or Exim is required. A stock Unix-like server already has internal mail more traditional ones also come with a full MTA already part of the standard installation. Unix-based mail servers are built using a number of components because a Unix-style environment is, by default, a toolbox operating system. The comparison of mail servers covers mail transfer agents (MTAs), mail delivery agents, and other computer software that provide e-mail services. ![]()
