Choose Your Email Stack: Total Freedom
Your hardware is only half the battle. Because iRexta gives you full root access to your dedicated server, you can install any Mail Transfer Agent (MTA) or management panel you prefer.

While you can install anything on Linux, these are the most popular stacks our customers use for high-volume delivery.
An open-source mail server suite based on Dovecot, Postfix, and other open-source software. It provides a modern UI for administration and includes SOGo, ClamAV, and Solr.
The industry standard for hosting management. cPanel automates the configuration of Exim and Dovecot, making it easy to create accounts, manage DKIM/SPF, and handle forwarding.
The "Purist" stack. Run a bare-bones Linux setup with Postfix (MTA) and Dovecot (IMAP/POP3). Offers the highest performance with the lowest resource overhead for maximum raw efficiency.
A highly configurable Message Transfer Agent developed at the University of Cambridge. It is the default MTA for cPanel and is famous for its flexibility in mail routing and access control lists.
Self-hosted email marketing applications. These are not MTAs themselves but sit on top of your server (usually connecting to Postfix/Exim) to manage campaigns, lists, and bounce processing.
A project that aims to make deploying a mail server easy. It turns a fresh iRexta Ubuntu server into a fully functional mail server with a single command in just a few minutes.
How we handle software on bare metal
Unlike shared hosting or managed SMTP relays, we do not restrict what you install. Upon delivery, you receive full SSH Root Access to your server. You can install Docker, compile custom MTAs, or adjust kernel parameters for high-throughput networking.
Open Source: Solutions like Mailcow, Postfix, and Mail-in-a-Box are free.
Paid Software: If you choose cPanel/WHM, Plesk, or DirectAdmin, we can provision these licenses for you during checkout for an additional monthly fee. For specialized software like PowerMTA, you must bring your own license.
