The question to ask is how you've configured delivery to Dovecot.
With LMTP you should be able to deliver many recipients in one
go, with just a small number of processes need to complete all
the deliveries.
Please post the details of the address class for the recipient
domain, and what transports are used to perform delivery.
Full (unmunged, with line folds preserved) "postconf -nf" and
"postconf -Mf" would be very useful.
