Best SMTP Server 5.5

Best SMTP Server 5.5 is a useful program which can be used as a local POP3/SMTP server for your corporation or as a desktop application on your laptop.

Its unique blend of features allows you to send mail from any mail client that is complaint with SMTP protocol. You can also configure it to be your local mail server. It will accept mail on behalf of your users and store it, until your users will retrieve it using POP3.

This server can be used along with virtually any mailer or email program. It has a lot of security features and options that allow you to protect the server from DDoS attacks as well as safely block spam and spammers.

SMTP and POP3 servers work as NT services therefore they will keep working even when no users are logged in. For software debugging and testing purposes, the program has a testing mode you can use to check if your email clients work correctly. All messages will be accepted, but will not be sent further. They will be immediately discarded so that you can check if your mail client works correctly according to SMTP protocol. 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. Newly added feature is advanced, parameterized mailing list management. This is not present in any of the other SMTP servers. Using this feature you can actually use this server as a mass mailer. You can create as many parameterized mailing lists as you like and customize each message that is sent to the member of the mailing list with up to 50 string parameters.

1. Local and Internet delivery of email messages for your users.
