I do use aliases file and I know what is it.
But it looks like not this case.
I want Cc: be rewritten like in aliases file defined in Cc: header,
not only those one that comes in "RCPT TO:".
And sendmail does not do it with Cc: field.
Yes, recipient that in Cc: field do receive this mail, all ok in this
way, but I want in MY mail Cc: field been rewritten as it is in

I want to see in my mail this email headers
to: user at domain.com
cc: user3 at site2.domain.com

Not this one:
to: user at site1.domain.com
cc: user3 at domain.com

Looked at postfix - same thing, no such feature saw there in documentation.
