Hi folks, This may just be a logical error that I've done, if so please point me in the right direction! I've got quite a few domains attached to my Email setup, so my setup is: Under Email Accounts > Domain I have the primary domain setup "example.com" I then setup an Email mailbox "email@example.com". I then setup a Domain Alias for "@example.co.uk" forwarding to "@example.com". So emails work if sent to firstname.lastname@example.org or email@example.com. The problem comes if somebody sends an email to "firstname.lastname@example.org", the alias works and it tries to forward it to the example.com, but because email@example.com doesn't exist (and I don't want it to exist!) it causes maildrop to get angry: Code: E29691036B1 2732 Sun Apr 15 18:14:59 firstname.lastname@example.org (temporary failure. Command output: ERR: authdaemon: s_connect() failed: Permission denied /usr/bin/maildrop: Unable to create a dot-lock at /var/vmail/example.com/fred/10677.0.vhost.) email@example.com Is there a simple solution to this, should I be creating a dummy catch-all to drop the mail or something, ideally I want these emails bounced with invalid recipient. Thanks in advance.
