Default e-mail address?

Do you mean the email account that reflects your username? This is your main user that was previously used as a default catch-all account. You really don't even need to use it and it doesn't hurt anything...just ignore it

 

Yes, but some users try to use it...

We were ignoring these accounts too, but one of our users recently logged into the webmail account for the default address, sent out a bunch of messages, and then called to complain that the replies couldn't get to him because the system-default was to bounce mail for these accounts.

It seems the mail interface should more clearly label this account as a "leave it alone" item, perhaps even removing it and the webmail link for it from the main mail management page.
