We have a customer, Acme, running Cent Os 4.5 with our software on it. When we encounter a problem we want to send mail to notify people. I am not asking how to do this because we already know how. The problem is mail. The host name is myhost (I am making up names again remember). When I try to send mail from it I eventually get returned mail, "the domain myhost.localdomain" does not exist (or something like that). I realize I have to change the hostname to myhost.Acme.COM but I cant' change the hostname via neat or in the files because it has other implications (mysql and some other software would be affected). I tried, without a high expectation, doing something like this: HOSTNAME=myhost.Acme.COM Mail tonychamberlain@lemko.com <etc> but the mail still came back because that just changed the HOSTNAME variable in my env, not actually the host name. Is there some way I can actually change hostname just for my environment to get mail sent, without having to change it for the whole system? </mailto:ve7whb@netzero.com></ve7whb@netzero.com></fedora-list@redhat.com></cummings@kjchome.homeip.net></fedora-list@redhat.com></fastfish@gmail.com></davidsen@tmr.com></cummings@kjchome.homeip.net></fedora-list@redhat.com></rab@nauticom.net></fedora-list@redhat.com></ignored_mailbox@yahoo.com.au></fedora-list@redhat.com></rab@nauticom.net></linville@redhat.com></fedora-list@redhat.com></linville@redhat.com></fedora-list@redhat.com></csnook@redhat.com></fedora-list@redhat.com></ignored_mailbox@yahoo.com.au></davidsen@tmr.com></fedora-list@redhat.com></davidsen@tmr.com></davidsen@tmr.com></davidsen@tmr.com></fedora-list@redhat.com></theatre@sasktel.net></davidsen@tmr.com></fedora-list@redhat.com></davidsen@tmr.com></davidsen@tmr.com></cummings@kjchome.homeip.net></fedora-list@redhat.com></davidsen@tmr.com></linville@redhat.com></fedora-list@redhat.com></pauljohn32@gmail.com></fedora-list@redhat.com></lesmikesell@gmail.com></fedora-list@redhat.com></linville@redhat.com></cl@isbd.net></html>
