Re: What makes Yahoo! a good merger candidate?

Sadly, it seems that more and more mail servers are RFC-apathetic :-(

And the admins even more so... It almost seems the larger the company 
the less likely to follow RFCs (IME).

There there's people like spamcop who think that RFCs are ok for some 
things but not for others :-(

</sigh>

Yee. Hah.  They 250 for a probably-nonexistent account (unless that
one actually *does* exist? :)


They're also the first mail server I've ever connected to that won't accept 
user () domain tld and insists on <user () domain tld> instead.  So, I'm not 
surprised to find that they 250 everything you type in.

I guess RFCs are even more meaningless now than they always have been.   :-(

BTW, privately I was informed that the *real* address is security () yahoo-inc com.

Who knew.
