Кратко: Fast and secure SMTP/POP3 server. Lots of features against spam and DDoS.
1st Mail Server is a fast and secure Professional SMTP/POP3 server program. You can use this program in many environments ranging from a corporate mail server to a standalone SMTP relay for your laptop. Any standard mail client can be used to send email using this server. SMTP and POP3 servers work as NT services therefore they will keep working in the logoff mode. For software debugging and testing purposes, the program has a testing mode you can use to check if your email clients work correctly. You can have multiple SMTP gateways in your server if you travel a lot with your laptop. This way, even if you cannot deliver your email directly to the destination, you will be able to still send it using one of the gateways.
