SES problem : Emails routed to SES incorrectly.

Hi,

I've got a problem where some users are reporting emails being bounced back to them as undeliverable due to "mailbox does not exist".

What I think has happened is I verified a domain so I could send email "from" that domain. But now, if someone else is using SES to send email, SES intercepts the email, cannot find a mailbox so returns it as undeliverable. I don't want to receive emails via SES, why is SES intercepting them and how do I turn it off?

Thanks in advance,

Tony.
