Thanks to this program you'll be able to have your own email relay server, managing to relay your email directly (without passing through your ISP), furthermore, you will be able to access your mail whenever you want, without having to worry about IP changes. Since you control the mail, your privacy will increase, because you will be able to be sure that no filters are reading what you send.
Furthermore, 1st SMTP Server practically doesn't need configuration because the default parameters that it includes are more than enough for the mail server to be able to work once you include your domain and a few personal details.
Among its functions, it will allow us to perform mass bulk emailing for publicity campaigns. But we advise that anyone that uses mass bulk emailing to do so with moderation, because if they over do it, you could be tagged as a spammer.
All in all, if you need an application to manage your own email relay server, download 1st SMTP Server.
