The mailFISH comes to you as a small application which has to be downloaded and installed. A so-called POP3/SMTP proxy acts as a local mail server and forwards your mail communication in an intelligent way. If your mail servers can be reached directly, this direct connection is used. If, however, no direct connection can be established your mail traffic is translated into HTTP and securely tunnelled through the server-side part of the service at www.serFISH.com.
In the free basic version of the service, up to 30 mail messages a day can be tunnelled. “It is important to note that of course only messages that go through our servers are counted.” says Jürgen Kuster, the founder of serFISH.com:
The main advantages of the mailFISH are the easy and well-documented setup of the client as well as the fact that it does not require access to a personal web server. Companies that want to provide many clients with the service can also set up their own local mailFISH tunnelling server. serFISH.com does not log any passwords, message content or other kind of sensitive data. SSL is used to secure the communication between the mailFISH client and the relaying server.
