The SMTP Relay Server is a Windows application that allows email messages to be sent directly from any computer to recipients' mailboxes. It supports various email clients for sending both individual and mass emails.

SMTP Relay Server is compatible with any mailer or email program that's operating on the same computer or on a separate system that's using the TCP / IP protocol. For traveling laptop users who are constantly changing their internet service providers (ISPs), SMTP Relay Server can be used as a gateway SMTP server. This means that it can either send your messages directly or redirect them to other SMTP accounts when direct sending is blocked by the current ISP.
The best part about using SMTP Relay Server is that you don't have to change the email program you're already using. You can easily integrate it with your current program by using the IP address "127.0.0.1" instead of your current SMTP host.
SMTP Relay Server also offers a lot of security options to protect your machine from hacker attacks and filter out spam. This makes it a reliable choice for anyone who wants to keep their emails safe and secure.
