[Bug-mailfromd] Deleting and adding the same recipient

[Mehmet Avcioglu <mehmet@xxxxxxxxxxxxx>]

Hello Sergey,

The following during `envrcpt` leaves the mail with no recipient.

        rcpt_delete($1)
        rcpt_add("alias@xxxxxxxxxx")
        rcpt_delete("<alias@xxxxxxxxxx>")
        rcpt_add("alias@xxxxxxxxxx")

Can you confirm that this is the expected behavior? 

Thanks
