I also check the headers of the emails I send from the machine itself when I telnet to postfix. indeed the email goes to my old mail server then to the new mail server. I checked the file /etc/postfix/transport and it was all commented but I added as you suggested <a href="http://mycompany.com" target="_blank">mycompany.com</a> smtp:smtp:ip_adddress_of_my_new_exchange I restarted postfix. but the header of any test message still goes to the old mail server... any idea please? --- On Fri, 25/4/08, Ilya Meylikhov <<a href="mailto:rage_q3@mail.ru">rage_q3@mail.ru</a>> wrote: > From: Ilya Meylikhov <<a href="mailto:rage_q3@mail.ru">rage_q3@mail.ru</a>> > Subject: RE: [Nagios-users] smtp server that nagios uses > To: <a href="mailto:melanie_pfefer@yahoo.co.uk">melanie_pfefer@yahoo.co.uk</a> > Cc: <a href="mailto:Nagios-users@lists.sourceforge.net">Nagios-users@lists.sourceforge.net</a> > Date: Friday, 25 April, 2008, 3:44 PM > You can change the /etc/postfix/transport to accommodate > your needs.
