autodiscover.xml erro response

Hi,

After the upgrade to version 87xx we receive complains about spark mail and I think that is because of autodiscover process.

I read the KB about autodiscover and at the end the article says that we should test de URL https://server/autodiscover/autodiscover.xml. When I try to test I get an authentication request and after login I get this error:

Invalid XML Request - Error: Domain does not exist.
   at MailService.Remoting.Mail.GetDBFoldersDomainStatic(String domainName)
   at SmarterMail.Protocols.AutoDiscover.AutoDiscoverProcessor.ProcessAsync(),

Its some think wrong it this reposnse, right?

Regards,

Autodiscover is only for mailbox holders on your server to configure their client application to connect to your server and retrieve/send their email.

Autodiscover should have NO effect on outside mail servers and interaction such as exchanging mail with your server.

Things that affect communications between your server and others can include SPF, DKIM, DMARC, TLS connectivity, and your server's reputation on outside block lists or reputation regarding spam and abuse.

Hi J. laDow,

Thanks for your response, I know what is Autodiscover. The point is: after the upgrade to last version (from 8667) Spark Mail clients (mail client like outlook) start to get an error on login and I think that is because the SM autodiscover its not working well.

That would mean you're most likely having issues with how the new version handles SSL certificates and whether or not you have SM manage your certificates. There were MAJOR changes to how SM operates in this fashion. It's one of the reasons we've held back upgrading yet.

Autodiscover relies a lot on the certificates for determining legitimacy of the endpoint offering the autodiscover response.
