Is there no general wishlist area for Dovecot then? I didn't necessarily expect the functionality to be packaged with Dovecot, but thought that somebody might pick up the idea and write a plugin for it if it was written down somewhere. From a privacy/security perspective, making sure deleted email isn't recoverable does have real value for some people. I did consider FUSE. I might tackle that one myself. I don't really have the expertise to modify Dovecot it's self though. -- Mike Cardwell https://grepular.com/ https://twitter.com/mickeyc Professional http://cardwellit.com/ http://linkedin.com/in/mikecardwell PGP.mit.edu 0018461F/35BC AF1D 3AA2 1F84 3DC3 B0CF 70A5 F512 0018 461F
