Email address - compromised?

[#1]

I have just received three emails from PlusNet;
One to postmaster, one to the usual email and a third to a specific email account inforning me that my new email address will be ready in 30 minutes.
Only thing is the email address is one I created many months ago. I did create a couple of new addresses over the last week or so and already received notifications about those.
Is there a problem or could this email address have been compromised? I have a strong passowrd containg letters, capitals, numbers and special characters.

It's part of a problem fix, nothing to be concerned about. Basically we've performed some maintenance to clear the status of some mailboxes which were stuck in a "pending" status, that included yours. As a result of this you received these notifications.
Sorry if this caused some initial concern.

I assumed that it was pobably something like that but in case not wanted to make you aware if it.
Thanks Adam.
