Maildrop is available at http://www.courier-mta.org/maildrop Although it is the default LDA for the courier mail server, it also works as a standalone LDA. The install script can even build an rpm package if you prefer to manage software that way. Maildrop can be used with sendmail as a drop-in replacement for procmail. It has better maildir support than procmail and it has filtering capability using syntax that looks a lot like shell script language with a little bit of perl thrown in. To use dropmail with sendmail, make the following change in your sendmail.mc file, then make etc. ---%<------------------------------------------------------------------------- dnl FEATURE(local_procmail,',procmail -t -Y -a $h -d $u')dnl dnl # replace above line with below line to use maildrop instead of procmail FEATURE(local_procmail', /usr/bin/maildrop', `maildrop -d $u')dnl ---%<------------------------------------------------------------------------- A default system wide configuration file for maildir style mailboxes might look like the following: ---%<------------------------------------------------------------------------- # file: /etc/maildroprc # system-wide settings for maildrop SHELL="/bin/bash" SENDMAIL="/usr/sbin/sendmail -oi -t" logfile "/var/log/maildrop.log" DEFAULT="$HOME/Maildir/" ---%<------------------------------------------------------------------------- In the above configuration, the users should be a member of the same group and the group should have write privileges to the logfile.
