This really isn't about Exchange, but felt it was close enough. Advance apologies. Working for a company which has Hosted Exchange. The internal domain name is the same as the email domain name (eg, mycompany.com). The MX records point the the 3rd party provider. My goal is in this project is to generate alert messages from a couple network devices. Unfortunately when specifying the Hosted Exchange SMTP server, I can not provide authentication information (user/password) to the network device. All of the popular public SMTP requireauthentication obvious reasons. This lead me to set up an internal SMTP server on a 2008 R2 machine. My problem in using the internal SMTP server to generate emails. Any emails with the company domain will get queued and will not deliver. Basically I want to be able to send emails to known email account for our company. Will provide more information if requested. Thanks

Any emails with the company domain will get queued and will not deliver. Basically I want to be able to send emails to known email account for our company. Will provide more information if requested. For what reason are the messages remaining enqueued? That would seem that the target server is returning a 4xx status. Have you checked the SMTP protocol log to see what's happening? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hello iwishiknewmore, You mean you want use the internal smtp server send email to your Exchange Server, right? If so, you can follow this to set on your Exchange Server.

Which may be the problem. :-) "192.168.6.25" is the IP address of your SMTP relay, correct? Is it configured to act as a SMTP relay for the domain mycompany.com (you can't use the GUI to set it to realy for the domain "*") and to send the messages for that domain to a smart host (which should be your Exchange server)? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hello, Do you have an appropriate MX record and A Name host that points to your hosted Exchange in your Domain's Internal DNS zone? I'm guessing you have split brain DNS, right?Miguel Fra | Falcon IT Services, Miami, FL www.falconitservices.com | www.falconits.com | Blog

Regardless if the To and From are identical email addresses, I am unsuccessful in sending email using mycompany.com using this smtp server. The issue is using any account that is mycompany.com.

Since the Exchange is hosted, the MX records point to the hosted provider. I don't have A Name host that points to the hosted Exchange within DNS. Unfamiliar with split brain DNS.

Okay, but what about the other part of the question about how the IIS SMTP server's configured? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

By default if Relay restrictions was not to Allow all computers which successfully authenticat to relay, regardless of the list above. http://blogs.technet.com/b/exchange/archive/2006/12/28/3397620.aspx I tried both setting with same results. My intention is not to use it as a relay, which I am aware of. If there is a best practice approach to this, I am open to suggestions. I have tried 3rd party smtp application with same results.

If you're not using the IIS SMTP server as a relay then you expect the messages to be placed into the "drop" directory. Since you say that the IIS SMTP server is allowing anonymous connections to relay, I'm asking how you've configured the domain on the IIS SMTP server in the IIS Manager. It should be present as a separate domain and exist as a "Remote" domain. Check the bos on the domain that sys "inbound messages can be relayed to this domain". You can use DNS or a smart host, but if you use DNS the MX record will have to be in your internal DNS (that's not something that's normal). --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

I appreciate your help on this and this is the the part I am not experienced with. At this point I am assuming it is safe to say i do not have the setup you are referring to. Is there any link on proper setup.
