report a problem

As the results of recent wild email "worms" clugging the internet, 
my smartlist has taken off hundreds of good email addresses off one 
of our research discussion lists (15% of total) due to repeated SMTP
connection failure (time out), and the mail delivery has become VERY
SLOW (for a mail it used to take 3 minutes to distribute, it now takes
5-7 days!).

Anyone else experience similar?

Although I can find those wrongly removed addresses from the log file 
and "manually" (with a script) add them back, I wonder can this
community do something?
