[Dovecot] deliver & override homedir

Hi

We're in the phase of converting our existing unix-based users to virtual users.

Goal is to make mail-spool totaly independent of home-spool. For that reason, NO files can be written to home. I've solved the problem for all files, except for .dovecot.lda-dupes.

I can see in duplicate.c #define DUPLICATE_PATH "~/.dovecot.lda-dupes"

I thought being clever and override in the userdb passwd following

args = home=/var/spool/mail/%1n/%2n/%n

but deliver totaly ignores that.

does anybody has tips?

kind regards Arne
