Sendmail X

If you require a robust and efficient message transfer system, consider Sendmail X. This software is modularized and consists of five (or more) persistent processes, four of which are multi-threaded. Additionally, it features a central queue manager that controls SMTP servers and clients for receiving and sending email messages. An address resolver is also included to provide lookups in various maps, such as DNS, for mail routing purposes.

With its main control program that starts the other processes and monitors their execution, Sendmail X ensures seamless operation. The queue manager effectively organizes the flow of messages through the system and guarantees no overloading of local or remote systems by implementing central control instances.

Configuring this software is simple and straightforward thanks to its easy-to-understand syntax. Furthermore, it's designed as a secure and efficient mail gateway without content modification capabilities, such as address masquerading.

Finally, the latest version features improved error logging for STARTTLS problems and a libpmilter fix. Try out Sendmail X today and revolutionize your message transfer system.
