Any PermittedHost Email Security Change Lately?

UPDATE.

I am now checking with our IT if the SMTP corporate server has the correct relay authorisation for the new server. I may have overlooked this issue.

Hello,

Om my previous report server, I had not set amy DefaulthostName nor PermittedHost.

This allowed us to create subscriptions that get sent to our business partners with a long ever changing lists of email addresses and domains.

All server are build 2175, they ahve the same rsreportserver.config setting for the email portion. Problem is that on 2 of the servers, the email with a domain other than our internal domain do not get sent with error "The email address of one or more recipients is not valid". It works on the third server.

I tested our SMPT server from another application and it does send emails to external domains so the problem is really on the server side.

It is vey important because subscriptions are managed by a few business analysts, they spend a lot of time creating lot of subscriptions and the domains change often.

I tried on the dev server to define cox.net as Permitted host and send myself a report to my private email, it also returned the error.

Any idea as where to look at? is ther a specific CDO setting to allow relay?

Thanks,

Philippe
