The problem was not postfix (of course), it was that I was modifying the mbox file using postlock $MBOXFILE sed -if $SCRIPTFILE $MBOXFILE which in fact replaces it, I am now using: postlock $MBOXFILE /bin/bash -c "sed -f $SCRIPTFILE $MBOXFILE|sponge $MBOXFILE" # not sure if bash subshell is necessary? and also comparing the inode before and after - if the inode changes (which is not normally the case) then I restart incrond. The use case is my home-grown quarantining system. Mail server periodically emails me about quarantined emails - I can reply to these emails using short codes, this reply is placed by postfix in the monitored $MBOXFILE. When $MBOXFILE changes, incrond triggers a script which looks at the latest email in it and interprets it to take the necessary actions i.e. removing unwanted mails from quarantine, releasing wanted ones, whitelisting sender etc.
