I have a requirement to let Smtp virtual server receive incoming emails and send it to the drop folder.

the domain of the SMTP is different than the local domain. I created an alias. but it did not work.

any help

What is the error that you are getting when you try to send emails through IIS SMTP server ?

Are you trying to send emails from an application to drop it to the SMTP server ?

Check if you are getting any error on that application

Have you configured relay permission on the IIS SMTP server for the app from which you are trying to deliver the emails

Check the size of the emails that is delivered from the app , because the default size limit of the SMTP server is 1024 KB and you need to increase the value if the message size is more than 1024 KB 

I am not getting specific error, the bounce back message indicates "#5.2.0 smtp; 5.4.7 - delivery expired"

let me explain the scenario.

I have a hosted Internet SharePoint which is installed in different AD forest than mine, mine has Exchnage 2013, the hosted sharepoint does not have Exchange organization. the required is to configure the incoming mail settings in the SharePoint. to do this I installed SMTP virtual server in the front end servers, from network part everything is configured by the hosted organization.

now the hosted SharePoint portal server is in windows NLB with 2 servers (both have SMTP virtual server IIS 6). the SharePoint local domain is different than the SMTP domain I need to receive incoming emails in. I created an Alias. under domains in the IIS 6 console.

now all messages are received in the Badmail folder.

in the properties of SMTP Virtual server in the delivery Tab  in the advanced tab, when I put the SMTP domain name in the Fully qualified domain name, and press on Check DNS it give me this error message "SMTP Configuration: The domain name is not valid"

 

Hi Mashhour,

Please post your query in the IIS Forum http://forums.iis.net.

You must have same valid Alias to get email from internet and make please share your mail server details .I would suggest let Exchange server manage send & receive email instead of virtual SMTP server and in share point you need to configure SMTP server details .

Hi,
