Introduction

mailfront-imapfront-auth-dovecot is a program to modify the MAIL environment variable according to dovecot imap requirements in order to access users mail storage.

Dovecot uses colons as internal field separators; however, since v1.2rc6, it allows colons occurrences via escaping (as : → ::). Before passing such mailbox paths via MAIL environment variable to dovecot imap, this wrapper performs such escaping.

From original MAIL environment variable:

/home/USERNAME/MAILDIR/mail:box:user

To:

maildir:/home/USERNAME/MAILDIR/mail::box::user

Or:

mbox:/home/USERNAME/MAILDIR/mail::box::user

Changes

19 Nov 2010 GMT +8 : Version 0.04: Use strcpy instead of strcat for initial maildir: or mbox: as using strcat might cause the funny string prefixed in some systems; Added mailfront-imapfront-auth-dovecot.sh; Place back gcc optimizations in Makefile as previous break issue is due to strcat
18 Nov 2010 GMT +8 : Version 0.03: Remove gcc optimizations in Makefile since it break some systems
13 Nov 2010 GMT +8 : Version 0.02: Support mbox format; Skip modifying $MAIL if starting string is mbox: or maildir:
