1st Up Mail Server is a powerful email server that has been designed for small to medium-sized business networks. It is simplicity itself to install and set up. Among its impressive feature list is anti-virus support, anti-spam mechanisms, unlimited domains, remote administration, multiple mail box collection, address aliasing, flexible scheduling, attachment removal, mailing lists and powerful routing filters. Boasting features simply not found on other mail servers, such as e-mail reminders, mail scanning, powerful filtering functions and auto-response systems, it still manages to have a small resource footprint allowing it to run on relatively low specification machines. 1st Up Mail Server achieves all this with some degree of style.
