Return code from EXPN

Hello,

When Exim 4.05 refuses an EXPN, it returns a 550 code. Since 550 usually
means something like 'mailbox not found', is 550 the most appropriate code?
Sendmail, qmail and postfix all seem to return 502. Should Exim do the same?

Thanks

Only the first digit of an SMTP response code should be interpreted by a
sender-SMTP when determining its actions - the remainder are for human
interpretation.
