Yes, in general, you should do it for both, AND you should do it with an integrated system so that a temp reject by one MX is understood by the other when a resend is attempted (either too soon or after sufficient wait.) > I did a test run on my test server and some ( not all only small > percentage ) mail once temporarily rejected would slip > through from my secondary mx. > This is just some thing I am looking into at the moment and > may not use at all but I thought it was worth a look Yes. And if you implement on 2nd MX then it really should not temp reject something already rejected by other MX sufficient minutes ago. -- Herb Martin, MCSE, MVP [EMAIL PROTECTED] http://LearnQuick.Com 512 388 7339 -or- 1 800 MCSE PRO Accelerated MCSE in a Week Seminars -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
