In the past few days (the problem did not exist before then, and I have done nothing to change my preferences or account settings)I have been receiving the following message every few minutes. I don't know whether I'm missing valid mail or what is going on. Anyone know?

The following message to <[email protected]> was undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 550-'<[email protected]>: Recipient address rejected: User unknown in virtual mailbox table'

My first reaction is that someone is sending out junk email with your
address on it, and you're receiving the error messages.

Is it *all* from cogeco.ca? Is that *your* ISP? You may want to check
with an administrator at cogeco.ca and see if they can determine why
you are getting these, they may have records.
