Hi,
Wietse: thanks for your quick reply :) !
We have the following internal clients:
- R&D Linux sendmail clients
- some special_home_brew websolutions that endusers maintain
- NetApp storage systems
- etc.
Mail path:
Internal_clients->my_postfix_mailrelay(s)->external_receiving_mailserver
We're not receiving any external mails...!
How do I best setup a loadshared failover postfix mailrelay solution for
this on RHEL6 ?
thanks in advance :-) !
