Nope. One Smart Host.

Provided it's not down for a seriopusly long time, the SMTP retries
will resend the mail after the server is available. You could solce
this by clustering the servers, but that's a bigger discussion for
another group.

My IIS server has to post Email to our exchange servers.
I'd like to put the two servers as smarthost
but It's always refused by IIS ?

If it's not possible, how to do not to loose email when one of the
exchange servers is down (maintenance,...)

Why can there be only one smarthost?
IIS shouldn't care about that. You should be able to put in many smarthosts
similar to Exchange. In testing it locally, it's the GUI that doesn't like
that but if I use some other method, I can enter that in.

You should test this yourself before relying on it, but basically you need
to look for and set the appropriate smarthost key in the metabase either via
script or via metabase explorer.

A script like this should do the trick.

That's my $0.04 anyway. If Microsoft doesn't support it, that'd be another
matter altogether although they really should clean up the metabase and
cause it to only hold one value if that's the case ;)

IIS5 had this as a valid configuration IIRC. IIS6 I have not heard any
different details.

My advice? If this doesn't work for you, consider using a different MTA or a
different submit process. i.e. If you currently have your code submitting
locally from the webservice, you can change that to use the Exchange servers
directly in the code vs. how it's configured now.



Good luck,

Al
