I love my Helm and have been impressed with how flawless it has been. One aspect has been a real pain to manage though- aliases.
1: One user with multiple domains. We have a few family domains, my last name, her last name, her last name - my last name and a common mis-spelling of my last name. When I hosted with a third party mail host we had a few mail boxes and aliased all the domains to end up in the appropriate boxes. At the moment I have no less than 6 mailboxes to accommodate all the domains. It doesn’t make any sense and needlessly complicates things when we send outgoing mail.
2: One alias to multiple mailboxes. Whenever we expect mail from some source that we both want to know; the Daycare mailing list, the homeowners association, emergency alerts from the power company… I previously used an alias that went to both of us. Here too I had to create another mailbox for this.
