Mercury/32 Mail Transport System - Version 3.01a The Mercury MTS is a proven, powerful Internet mail transport originally released as a set of NetWare(tm) NLMs, designed to run on Novell NetWare file servers. This version takes full advantage of the threading and pre-emptive multitasking of systems such as Windows 95 and Windows NT to provide an extremely smooth, powerful mail transport with a host of features, yet one that has negligible impact on the system on which it runs.
