I've had this problem for the past 2 years, initially 
reporting it on a LUG mailing list back in .ug.

Since I (like many others) use my own mailer on my laptop, 
and it's guaranteed anything to Yahoo's mail servers will 
encounter 421 error 95% of the time, a simple 'exim -qf &' 
run 3 or 4 times (it cycles through different MX's until it 
finds one that's actually doing what it's meant to do) 
eventually hits home.

I think (I may need corroboration) that Yahoo are also rate 
limiting bandwidth to some or all of their mail servers. It 
once took me a day to send an 8MB file over to Yahoo (no, 
really), when the same file arrived in .ke in less than 5 
minutes from hitting "send". There are many incidents I've 
experienced like this.

Complaints have yielded diddly. I've learned to live with 
it... if you can't beat them...

Mark.
