I hope I am at the correct list for my question. I am brand new to postfix moving from sendmail and have the following problem.
My domain mydomain.co.za is hosted by my ISP. I have a internal mailserver in the office newly installed with postfix, dovecot and mysql and setup my mydomain.co.za as a virtual domain. All mail going out from inside the office get locally delivered to the internal machine and mail get fetched from the ISP. Now I have one user never getting to the office which mail I would like to deliver to the ISP and not locally. So all addres...@mydomain.co.za must be delivered local except mob...@mydomain.co.za must get delivered through my relayhost to the ISP. Can anybody point me in a direction how to this? I have moved from sendmail because I was let to believe that I could easily do this in postfix. Thanks Isak Badenhorst
