Clustered R5(.08) servers issue

I'm working on an issue with Clustered R5(.08) Servers.

SMTP is used for all mail within the domain and the Configuration document for all servers states "Cluster Failover: Enabled for last hop only".

My concern is that this parameter is for Notes mail via NRPC rather than SMTP.

When testing this and failing over one of the servers in the cluster where the recipients mail db (replica available on other clustered server!), it still attempts to deliver the mail via SMTP to the failed server, after two SMTP connection attempts the third attempt produces the following router message;

"Router: Error transferring message (messageID) via SMTP to (servername) 550 5.7.1 Unable to relay for (recipient name)"

The recipient is within the Internet Domain and Notes Domain specified in the Global Domain, the same as the sender.

I've also removed any form of Inbound/Outbound restrictions in the Configuration document to ensure that it is not a restrictions issue.

My query really is, is this the way it is supposed to be? Have I done (or not) something stupid? Will I have to go back to good old NRPC to have the desired affect?

Would appreciate confirmation of my findings or any thoughts on possible resolutions.


Why don't you have failover enabled for all hops, is one question I have. However, you could try putting your servers in the allowed to relay fields of the config doc. My best suggestion is to route via NRPC internally. For Notes messages, this really is the best way.
