Long live courier

Phew, turned kind of hot yesterday as I was upgrading my mail server (Courier .47 to .49). After a recursive configure and make, things got messy when I started to optimise permissions (and hence increasing security). Issues I've encountered so far:

   
• Public folders need the sticky bit, otherwise it's difficult to keep track who's done what.

   
• Personal folders can remain under 1 account provided they have permissions 0700.(so no sticky bit there)

   
• If you've tried your own email account long enough bashing it to pieces, Courier marks it as Temporarely Unavailable. Only thing to do then is just go into /var/track/ and remove your account in there.

   
• The file respawnlo, can be modified to restart once every x days (finally found that)

   
• maildirshared contains the public folders for everybody

besides those discoveries, I've never had a mailserver that good. I've tried qmail/courier-imap and sendmail/wu-imap and hopefully I don't start a religeous war here but much too difficult to install and to administer.
