Package: postfix
Version: 2.5.5-1.1
Severity: grave
The logic in postfix.postinst that attempts to ensure there are
certain entries in the master.cf file will corrupt an existing
master.cf that is not terminated with a newline character. It is
contained in this section of postfix.postinst....
while read line; do
serv=${line%% *}
if ! grep -qE "^${serv}[[:space:]]" ${MASTER}; then
[ -n "$echoed" ] || echo "in master.cf:"; echoed=y
echo " adding missing entry for ${serv} service"
echo "$line" >> ${MASTER}
fi

... You can see that when echo appends $line to ${MASTER}, it will
have pasted it on the end of the last line.
In my case that caused my spamfilter injection point to silently fail
causing the mailserver to stop delivering mail.
An easy fix would be to stick a blank line in front of the added line
to ensure it can't be extending an existing line.

As a relatively new maintainer of postfix, I'm working on cleaning up the BTS.
This bug does not relate to any configurations the Debian project still
supports.
