Can you not limit the no. of messages sendmail accepts per connection 
and a queue limit instead? That's what i did with my similar setup but 
with exim as the MTA. Fetchmail copes with this gracefully. I had 
exactly the same problem every time I went on holiday and shutdown my 
local mailserver: with the huge volume of spam, fetchmai, would go and 
get loads of messages from my POP3 box, deliver them to Exim, which 
would then launch lots of spamd processes. The box would work itself 
into a corner until theer was little choice but to 240-reset it! Once I 
set the limits in exim, it's just a question of waiting a while.
