[jdev] SMTP-style relaying for XMPP?

I am actually looking at this right now as a sort of Push-style email. The only worry is that it will introduce SPAM into the XMPP network.

Essentially the XMPP server will need a SMTP gateway (which is a SMTP server itself), after that it should be peanuts.

What you could also do is to create a gateway that acts as an SMTP client and uses an IMAP4+IDLE client to get instant updates on messages (or use polling POP3 if you are really lazy) from Zimbra. After this, there is generally a 1-1 mapping of XMPP and email fields.

IIRC there is a SMTP gateway floating around the net somewhere, but I don't think any XMPP servers are hosting it right now.

Also remember that the target XMPP server will also need the SMTP gateway hosted. In the end you would get something like the following:

Client
   |
   |
   V
XMPP Server
   |
   |
   V
SMTP Gateway
   |
   |
   V
Internet
   |
   +--> Classical SMTP Server --> POP3/IMAP Client
   |
   V
SMTP Gateway
   |
   |
   V
XMPP Server
   |
   |
   V
Destination

Which is pretty attractive.
