You will see separate processes of exim like this:

2287 ?        S      0:00  \_ /usr/sbin/exim4 -bd -q1m
 2289 ?        S      0:00  \_ /usr/sbin/exim4 -bd -q1m
 2291 ?        S      0:00  \_ /usr/sbin/exim4 -bd -q1m
 2296 ttyp2    S+     0:00  |   \_ grep exim
29446 ?        S      0:00 /usr/sbin/exim4 -Mc 1LMLKK-0007es-NQ
30092 ?        S      0:00  \_ /usr/sbin/exim4 -Mc 1LMLKK-0007es-NQ
 2147 ?        S      0:00 /usr/sbin/exim4 -Mc 1LMLP9-0000YV-Ma
 2150 ?        S      0:00  \_ /usr/sbin/exim4 -Mc 1LMLP9-0000YV-Ma

The ones with the -bd -q1m are the daemons.  The others are instances
handling specific messages.  You can see what exim is doing running

Search Exim's spec.txt.gz for smtp_accept_max and you will find your
