[Freeipa-users] Postfix IPA

[freeipa at noboost.org]

Hi All,

Server:
ipa-server-2.1.3-9.el6.x86_64
sssd-1.5.1-66.el6_2.3

Client:
ipa-client-2.1.3-9.el6.x86_64


I've got Postfix working with IPA and to be honest it was actually very
easy. I simply setup a standard postfix server, configured the IPA
client and when mail was delivered, postfix detected the UID's from IPA
and delivered the mail. 

So I thought to myself, this is one of the most important services we
have. What would happen if the SSSD client failed for some reason on the
postfix server?

As expected the postfix server bounces the email back to it's sender.

Before I start investigating backup mail servers, different posfix
queues. Just thought I'd ask if anyone else has setup their one solution 
to ensure the safety of mail delivery with IPA?
