It might also affect spam detection.

Now, the main reason I dislike Exim is


Basically, when invoked as sendmail, Exim breaks the sendmail
compatibility by keeping the Bcc header, involving security
and/or privacy problems. And since this is by design, it won't
be fixed.

BTW, since it must accept 8-bit mail via this interface, it is
also broken as the mail may be sent to a MTA that doesn't announce
8BITMIME, since Exim doesn't know to do the conversion. :)
