Guide Review - Autoroute SMTP 1.1

To prevent spammers from abusing their email servers, ISPs allow only their users to send mail through them. They either require you to log in when sending mail or check whether you have connected through their own network. As long as you only have one ISP this is no problem. But if you connect to two different ISPs and they use the latter method of authorization, you need to continuously change the outgoing mail server settings in your email client. Or you use Autoroute SMTP.

Based on your connection, Autoroute SMTP automatically chooses the appropriate server. The choice is based on your IP address and that of the mail server and works reliably. If it doesn't, you can still change the server manually, still faster than changing the account settings in your email program.

While Autoroute SMTP does not support SMTP authentication, this is an omission that can be lived with. If your outgoing mail servers support authentication, it doesn not matter from where you connect.
