I am working on a custom rbl type milter and thought I had a memory leak in
my code.... However, I while stumbling around trying to track it down, I
was a bit perplexed as to where it is. So I thought I would try with the
sample milter to see if it behaved as expected. Much to my surprise, it
too seems to just keep growning in memory consumption. i.e. blast a few
emails at it, and the process grows and grows with additional email.

Am I safe in assuming the sample milter in the documentation is free of
error ? This is from
/usr/src/contrib/sendmail/libmilter/docs/sample.html
with the following simple Makefile
CSRCS = samp.c
OBJS = samp.o
SRCS = ${CSRCS}
CC = cc
CFLAGS = -g -pipe
CFLAGS = -I/usr/include/libmilter -pipe -g
TARGET = rbl-sample
LIBS = -pthread -lmilter
all: ${TARGET}
rbl-sample: ${OBJS}
${CC} ${OBJS} -o rbl-sample -L /usr/local/lib ${LIBS}
I thought I would try here first as I didnt find any reference to said
problem in comp.mail.sendmail.
