Sendmail, can I make it send mail to 2 different accounts?

[Edmund <edmund wildworld net>]

I have a client that would like all mail that he receives to be sent to
2 different accounts.  Is this possible ?

For example, right now, I forward any mail he gets to his mail
johndoe hisdomain com 

Hs would like to ALSO get it at another account like
johndoe2 anotherdomain com 

Can this be done with Sendmail ??

Thanks in advance for any help.

C'ya,
