Subject pretty much says it all. My MX and the perl.org MX have had a falling out. Now all I get is this:
[canker:~]$ telnet mx.develooper.com 25
Connected to mx.develooper.com.
Escape character is '^]'.
451 Sorry, too many connections from <censored>, try again later
Connection closed by foreign host.

So the smokers have had their plugs pulled.
