linux default iconThunderBridge Publisher's description

ThunderBridge is an extension that enables delivering e-mails directly (P2P) by-passing mail servers.

ThunderBridge allows sending e-mails directly (P2P) by-passing external e-mail servers.
Therefore it enables for delivering e-mails with really large attachments (e.g. 800 MB), not to mention an improvement in privacy and safety of e-mail transmission, which traditionally requires 3 independent transmissions over 4 independent computers so that it is vulnerable to be intercepted and copied.
When you send your e-mail traditionally (via SMTP/POP3 channels, see Wikipedia for an excellent explanation) it goes like this:

1. from your Thunderbird to your external outgoing mail server (SMTP),
2. from your external outgoing mail server to recipient’s incoming mail server (SMTP),
3. from recipient’s incoming mail server to recipient’s Thunderbird, on recipient’s request (POP3 or IMAP).

With ThunderBridge your e-mail shall be delivered directly (P2P) to recipient providing that:

1. recipient also uses Mozilla Thunderbird with ThunderBridge, and
2. both you and recipient are located at the same private network, or
3. at least one of you has a public IP address.

How does it work?
It’s simple: Your recipient’s ThunderBridge is ready for connection and when you click “Send" (via ThunderBridge) button the connection with the IP address of your recipient is established and your ThunderBridge uploads your e-mail.
Since this is a direct P2P connection you can send messages of any size not worrying of exceeding mailbox quota on any external e-mail server.
Moreover in case you and your recipient operate on the same local network the e-mail will not leave this network and will be delivered even if this network is isolated from the Internet.

And if I don’t know what is my recipient’s IP address?
In such a case when you click “Send" (via ThunderBridge) button your ThunderBridge will send to the recipient a small “invitation message” containing your IP address and your e-mail address via traditional SMTP/POP3 channels described above and will await for the recipient connection.
When recipient’s ThunderBridge receives the invitation message it will connect with your awaiting ThunderBridge and will download your e-mail.

And what if neither upload nor download works?
Well, in such a case you can always send your e-mail traditionally (if it is not large) or perhaps call and ask your recipient to download and install ThunderBridge and run Thunderbird.
