I looks like your server is to slow to answer this huge amount of 
requests. :)

Now seriously. I do not know about Dovcot, but on my Cyrus 
IMAP/POP server I can configure how many connection it should 
accept at most. Google showed me, that Dovecot also could do 
this, e.g. client_limit, see [1]. A useful value depends on your 
user base.
