So Postfix stopped delivering emails to inbox after a few hundred successfully were received/delivered. Now they are all landing in queue (postqueue -p). I had a high number of emails coming in from different sources for resume applications sent out. Recieved well over 100 perfectly, than all of a sudden no longer receiving any, and can no longer send any.
Server: Postfix, amavisd-new, SPAMASSASSIN, CLAMAV, dovecot, nginx, debian9, roundcube, ispconfig.
It seems there is a long delay with the smtpd from the tail outputted below?
Here is some crucial tail information (in no particular order):

Already tried postfix flush, postfix restart.
Solution:
Seems it is fixed now. Fixed it myself.
sudo /etc/init.d/amavis restart
sudo /etc/init.d/postfix restart
