Your account gets 11 POP3 mailboxes. One of these is in the format
[email protected] where zen99999 is your username. You can then create aliases for this POP3 mailbox (via Customer Services) in the form
[email protected] (where xxx can be whatever you like - provided it doesn't already exist).
Your other 10 POP3 mailboxes are of the subdomain format.
I'd agree that the subdomain format appears a little clumsy, however I can't really see any other way to give customers the choice for the user-portion of their email addresses without causing conflicts with others - short of giving each customer their own unique domain (which would be a pain to administer). The disadvantage of the
[email protected] or
[email protected] type of format comes where you want a particular name for the 'xxx' portion and someone already has it!
Granted the subdomain method will generate conflicts as well where someone has already created a particular subdomain, but for those with families who want to setup a separate POP3 account for each member of the household, it means only having to resolve
one conflict instead of the potential of one for each family member.
I would think that anyone who is that bothered about their email address formats would tend to register their own domain (or should certainly consider it), as this has the added advantage of being ISP-neutral.
