Yes and no. Each milter call is allocated to a child at random:
(connect) milter call
(HELO/EHLO) milter call
(MAIL FROM) milter call
(RCPT TO) milter call (possibly multiple RCPTs)
(DATA) milter call
The "connect" milter call is handled by filter_relay
It knows the IP of the connecting client, and the reverse DNS lookup if it
exists.
The "HELO/EHLO" milter call is not handled by any MIMEDefang function --
probably because rejection on a HELO / EHLO would be unexpected?
The MAIL FROM milter call is handled by filter_sender
It knows what filter_relay knows, as well as the HELO/EHLO and MAIL FROM info
The RCPT TO milter call is handled by filter_recipient
It knows what filter_sender knows, as well as the RCPT TO info
The DATA milter call is handled by:
filter_begin
for each MIME part:
filter
filter_multipart
filter_end
So the filter_begin, filter, filter_multipart, and filter_end functions are all
called in the same child. The other functions may or may not be.
