I have a problem i’d like to fix.
I have a PostFix Server forwarding mail to a Domino server, which route it to the different OU servers…
The probleme is, when the master server fails, no mail comes in by SMTP.
I’d like to find a way to get it to work on failover.
As the master server is a Solaris, I was wondering wether I could create a Cluster with a Windows 2000 Server, that way load could be shared, and mail not lost…
So can I make a Domino Cluster with a Solaris and a Windows 2000 both running Domino 6.0.1??
If not, I’d like to forward the SMTP mail incoming to two different Domino servers, and that each could put the mail in the users mailbox, knowing that both servers contain all users, because one is the external access one.
What I mean is as if the external server had a domino directory saying the user mailbox is in his mail directory.
Does it sound clear or am I weird to think about something like that?
Thank you for your answers,
Regards,
Jean-Charles.

Domino Clustering works independently of the OS. So yes, you can cluster a Domino server running on Solaris with a Domino server on Windows 2000.
How you get your SMTP to send to the cluster, rather a named server, I’m not sure.

Thanx so I can create a Cluster containing my two servers, that would be cool…The only thing that could be a problem would be how will the cluster manage when I forward mail from the PostFix to both servers? Will Domino see it’s the same mail and only keep one?
I ask that because I cannot do the Cluster right now, I’m missing the second server 
but if it works i’ll get one ASAP.

SMTP incoming failover works different way (it is built-in SMTP feature)
You do not need any cluster
Just 2 servers and properly configured MX records in DNS
on PostFix you should setup SMTP Routing via MX - not forwarding.

Thank you for your help, but will the SMTP MX Routing work as I only have 40 users on Domino and the 760 others still on Outlook/Postfix?
I can so create a sub-domain domino.xxx.com and put two MX fields with the same “price” (5) and both names? that sounds great… that way I could keep my selective mail forwarding, and still use the SMTP load balancing… 
Seems reasonnable?
Subject: RE: Failover ability for a non cluster
Yes. Reasonable.
Only problem, that you can have troubles configuring Postfix server for MX routing.
I mean if notes users has the same local domain part in e-mail addresees than MX routing may fail since it’s also local domain part for PostFix.
sub domain domino.xxx.com means in your scenario that users should have e-mails like
user@domino.xxx.com but not user@xxx.com
