I have patched VpopMail 5.4.13 so that each user in a domain can have there E-Mail handled by there own set of .qmail files (in /var/vpopmail/domains/{domain}/{user}), this is a patch to 'int check_forward_deliver(char *dir)' in vdelivermail.c. This means for us when we delete an E-Mail address all the special delivery rules are also deleted (for that user). Is this patch of any interest to anyone or is this meant to be done another way ?
