Comment out the following line in /etc/mail/sendmail.mc: dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA') or change it to this: DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA') and rebuild the cf file: m4 sendmail.mc >/etc/sendmail.cf -- // Miles Davis - miles@cs.stanford.edu - // http://www.cs.stanford.edu/~miles // Computer Science Department - Computer Facilities // Stanford University [The following two posts answer a very similar but slightly different question.] From: Richard Keech Subject: Re: Chaining Mail Servers To: megan woods Cc: Linux Users of Victoria X-Mailer: Ximian Evolution 1.0.8 (1.0.8-10) On Thu, 2002-12-05 at 20:32, megan woods wrote: > Is it possible to configure Sendmail or some other mail server > software to relay all outgoing mail via another mail server regardless > of destination.. > Eg. > > Client --> MTA1 -->MTA2 --> Internet -> final destination. for sendmail on mta1, in /etc/mail/sendmail.mc add the line define(`SMART_HOST',`mta2.wherever.com') then rebuild sendmail.cf m4 sendmail.mc > sendmail.cf From: megan woods Subject: Chaining Mail Servers- Follow up..
