Reproducible: Always telnic.org have already created a plug-in that integrates .tel with Outlook. http://dev.telnic.org/pages/winoutlook/landing.html Lets have native support for .tel in thunderbird.

Not sure if that currently possible Gecko code can only lockup A DNS records. Wayne, probably this should move to some mailnews core component, what you think?

(In reply to comment #1) > Not sure if that currently possible Gecko code can only lockup A DNS records. Gecko's DNS support is quite low. It all depends on how this thing is working. Based on http://dev.telnic.org/pages/general_landing.html I don't think it would work with the current necko stack. I also think this request would be very well suited for an extension.

But extension use also Gecko code so again developer will bump against wall. .tel get information from NAPTR, TXT and LOC records.

There seems no blocker I can find, only mention of its limitation in bug 342242#c15
