Three reasons:

A) you check for a valid SMTP-AUTH on the server and did not use it in
your mailclient's config.

B) you made a typo in one of your local domainnames, you want to send
mail to, so exim "thinks" it shall send it to the external domain and
requests SMTP-AUTH for it (  --> A ) to avoid beeing an open relay.

C) you forgot to change your relay_hosts entries to you new IPs ( maybe
a typo )

A+B are very common problems.
