I need to setup an SMTP server that will accept requests to send from any e-mail address to any e-mail address. I want to use an authentication process to allow clients to connect to it with a username and password. Can I do this by setting up IIS? If no what is my best method of setting an SMTP server up with this?
Thank you,
Rob
Solution :-
Please check your mail logs and you will see the error there, You can find its location under mail sever properties logs. Also, Please provide details like weather you are using smarthost?
Event 4001 Typically, this problem occurs if the destination SMTP server performs a reverse lookup and if one of the following conditions is true:
* The IP address does not match the domain name that is used in the return address of the e-mail message.
* A pointer (PTR) record does not exist or is not valid for the source SMTP server's IP address.
For example, consider the following scenario. The domain name that is used in the return address of the message is source.com. You send the message to a different domain. The destination SMTP server then performs a reverse lookup on the incoming message. If the PTR record for the source.com domain does not exist or is incorrect, the destination SMTP server does not deliver the message.
Note If your Network adapter that is connected to the Internet is using a dynamic IP address, you may have to configure Exchange Server to route mail from the source.com domain through an SMTP connector to a smart host.
Note You can configure the Exchange server to reject incoming connections by specifying a domain name on the SMTP virtual server. When this is done, reverse lookups are performed on all connection attempts. This setting is available under Connection Control on the Access tab when you right-click the SMTP virtual server and then click Properties.
