The VPOPMail module only allows for setting the user and group used by VPOPMail system-wide. However, VPOPMail allows configuration of owneership on a per domain basis. As the quota support in VPOPMail has never worked well in the stable branch, this is useful to enforce quotas and also allows to add mail to the disk quota.
- The VPOPMail module should allow to set email owner according to the irtual server's owner.
- The VPOPMail module should possibly allow setting the mail directory for every virtual server.
