Alerts mailing list
The Bitcoin Protocol specification supports the broadcast of Alerts. An unofficial email relay is now provided that rebroadcasts these block chain alerts via subscription to the bitcoin unofficial alert mailing list . Alternatively, to subscribe via email send an email to firstname.lastname@example.org .
If you receive an alert you should immediately verify it is official by running "bitcoind getinfo", go to http://bitcoin.org  to find out more details concerning the alert, or join the #bitcoin IRC channel on freenode.
Alerts are independent of blocks or transactions, and have a defined time-to-live. The email relay polls bitcoind every 5 minutes and will continue to send alerts until the alert is cleared.
Please send any comments or requests to Gary Mulder .
