BACKCLICK Mail Transfer Agent 

The BACKCLICK MTA is an alternative way to send out e-mails without using an SMTP Relay Server. 

With this independent module, e-mails are sent directly to the recipient’s mail exchange server (MX) without the use of a relay server. Advantages include immediate display of any faults, and reports of successful attempts to send, as well as considerably higher speed for the delivery of the newsletter. 

The BACKCLICK MTA is scalable in a linear fashion, which should be familiar based on the way that newsletters are usually sent. Thus, the sending rate increases linearly with the number of BACKCLICK sending servers. A domain-based configuration of the BACKCLICK MTA handles the special requirements of some providers.
