Does anyone know of a reasonably up to date (i.e. still maintained) webmail application that can use local mbox files?
No. Why the fixation on mbox files? They're not very efficient for CGI or PHP use. Probably need to look for an application server webmail (Zope?) or one with some sort of daemon.
I have been trying a couple of webmail applications with IMAP servers (both UW Imap and dovecot) but the IMAP implementations are so awful that they make them very awkward to use IMHO.
Another IMAP server that I think handles mbox is imap4d from the GNU mailutils. I've never tried it (but probably should). http://www.gnu.org/software/mailutils/manual/html_node/mailutils_44.html
