Dear All,
I have been using centos 5.1 for quite some time as out DNS and mail server and been workin fine
i use sendmail as my mail server
i did setup a backup mail server as per docs and ran th dns test from http://www.checkdns.net
and it says both the mail servers are fine
but i would like to know the following
how would i really know if my main primary server is down all my mails r goin to my secondary mail server
and when my primary is up are the mails copied back to my primary
i did put down my mail server for abt 3 hrs cause cant keep it down for long but did not really see anything
also are there any websites that can chec both my mail servers correctly
apprecite and thnaks
A real simple test would be to bring down the primary and send yourself something from an outside address like yahoo or gmail. give it 10 or 15 minutes, bring the primary up and when you see the message to yourself, it should have a header from your backup server also.
Thanks scott i did test my mail setup by sending 2 emails from outside address by shutting down my primary mail server
and i could see that the mail was queued to my secondary
and after abt 20 min which is wht the queue time set by me the mail was perfectly delivered to my inbox
apprecite n thnks
actually my queue time ealier was set to 1 hr and hence i never waitied for 1 hr jus w8ed for 20 min to 30 min n hence was confused
thnks once again
regards fabian
Glad I could be of assistance!
