| I've set up two servers that act as backup MXs for
| various domains. In times when spam flood is increasing
| more and more, I tried to "load balance" them ..
|
| The MX-Records for the domains using this servers
| is set round robin, i.e.
|
| IN MX 10 realmail.customer.tld.
| IN MX 20 eximbackup.domain.tld.
|
| where
| eximbackup.domain.tld. IN A 10.0.0.1 [server 1]
| IN A 10.0.0.2 [server 2]
|
| So exim does the dns lookup for sending the outgoing
| mail and is (of course) querying/using all MX-Records.
| So far no problem .. but if the lowest MX is down,
| then the first exim server is sending the mail
| to the second one and that is sending the mail back
| again .. and so on ...
Maybe I found the solution myself ..
Could be
ignore_target_hosts server1 server2
the right thing ?
Regards,
Tom
