1st SMTP Server - is a simplest, easy to use SMTP mail relay server. It is used for relaying your email messages to its destinations quickly and easily. Nowadays, many Internet providers are closing their SMTP servers and filtering all the incoming SMTP traffic to fight Spam. They let everybody in from their local network. And filter everybody out who is not. This means that as long as you are using their services, your email client is working fine, but what happens when you go on a business trip or vacation and you want to send an email from an airport or hotel room? In most cases your SMTP server is not accessible to you anymore since you are trying to get to it from outside of your ISP's network. If you use our 1st SMTP server, you will not have that problem since it is going to deliver your email directly to it's destination bypassing your ISP's SMTP server.
