sendmail and backup mail server


I recently installed Sendmail 8.12 as my companies mail server. Our ISP has a backup mail server and I am wondering if I need to add something to my sendmail configuration so that we will receive the mail from that server should our in house server ever go down.

Without Sendmail in place how does your company connect/retrieve mail from your ISP?

We had an old Eudora Worldmail server which we swapped out for for the Sendmail server.

Right but say your sendmail server fails. Will you then have to configure each client machine to connect to the ISP's server, or can you run a backup server running postfix/sendmail/fetchmail etc to retrieve and distribute.

I guess I don't understand your question. Are you looking to create a "backup" mail server in-house?

I think the more appropriate term might be that it serves as a buffer; periodically I see messages in the maillog that it is relaying messages to our machine.

if you just want a backup server to get mail, if your server goes down, all you need to do is set up 2 MX records for your domain.

ie - linuxquestions.org in MX 10 smtp.linuxquestions.org
linuxquestions.org in MX 50 smtp.yourisp.org

smtp.linuxquestions.org in A 192.xxx.xxx.xxx

this will sets priority on the Mail Exchanger, so that it will attempt the 10 first, then the 50 -- ie if 10 does work.

hope this answers your question.

So I shouldn't need to set anything in sendmail to enable it to accept mail from this server?
