[Exim] RCPT TO 501 error (for address include space characte…

Hi,

I am trying to replace a sendmail or qmail box with a exim box.

The following command is accepted by qmail or sendmail.
rcpt to:<anyone any@domain>

But in exim, it has not performed by displaying the next error.
501 <anyone any@domain>: "@" or "." expected after "anyone"

Although transmission will be stopped, if MUA receives 501 errors,
it is not operation to desire.

Is there any method of corresponding by the exim side?
