Multiple SmartHosts in sendmail.

Jason Young — Tue, 18 Dec 2001 12:24:18 GMT

Can someone tell me if it is possible to set up multiple smarthost's in the sendmail.cf file? I have some critical unix boxes that send out e-mails often, I currently have them set to use a smarthost to send the mail. The problem is that if that smarthost is down the mail does not go. Can I set up a list of smarthosts that I could use in the event of the primary not being available? I could not find any reference to doing this on sendmail.org ..

Thanks in advance.

Thank you for that info, but I don't get anything back from that link. Is the document anywhere else ?

Hello,

To configure SendMail to use more then one relay, edit:

/etc/mail/sendmail.cf

file and simply specify the hosts separated by a colon with no
spaces. For example:

DShostA:hostB:hostC

SendMail will always try hostA first. If hostA does not respond,
or responds incorrectly, then SendMail will try hostB and then hostC.But it will not load balance

Separate each hostnames in the DS macro with a colon.

Hi Jason,

Try this,

quote //

To configure sendmail to use more than one Relay Server, in /etc/mail/sendmail.cf simply specify the hosts separated by a colon with no spaces:

DShostA:hostB:hostC

sendmail will always try hostA first. If hostA does not respond, or responds incorrectly sendmail will try hostB and then hostC.

//unquote

Hope this helps.
