I 've a domain and a server say mydomain.org
I need to forward all the mails i receive over here ie.
admin@mydomain.org , hello@mydomain.org , anything@mydomin.org etc.,
to another address which is admin@anotherdomain.org , hello@anotherdomain.org , anything@anotherdomain.org.
i'm using apache. How do i achieve it?

there are no login accounts like admin,hello,anything.. I want all the mails that come to my domain to be forwarded to anotherdomain which is on some other server not controlled by me. Also i dont want a copy of the emails in my server, dont mind if they are stored.

I'd you're receiving mail on that host you must have an mta. Ie, exim, postfix, sendmail, etc. Just put in a forwarding rule. Exim is very good for this purpose.

thanks.. I've postfix installed now.. i found the way to add individual aliases.
like i added admin@mydomain.org admin@myotherdomain.org etc..

but is there a way to specify this for any address? like all the mails to xxx@mydomain.org to xxx@anotherdomain.org in postfix ?

I'm not sure in postfix. In exim you'd skip the aliases and use rewrites.
