We work with a 3rd party partner for a specific application. This 3rd party vendor supports the application and we just support the server end (Windows 2003 Server Std). This server is in a workgroup (not in a domain). The network clients (in a Domain, not a workgroup) map a drive to the server through a batch file and can access the needed application that way.
The application is working pretty well except for the e-mail portion of it. The database queries are working fine; but, if one would like to e-mail a report from the program the following error pops up: "STMP reported: 5.7.1 Unable to Relay".
This feature did work until the vendor upgraded a piece of their software. The SMTP settings in the program are correct and have not changed. It has the fully qualified domain name of the existing Exchange server. Keep in mind that this Application Server is in a workgroup, not in a domain with the Exchange server.
Now other workgroup application servers that ask for an SMTP server address have the exact same thing entered in as the rouge Application Server and these other application servers are e-mailing information just fine.
Another PC/Client however gets a different error message when trying to email from that rouge application. The 2nd error message sates that XXX version 7.05 is not installed. Go to the downloads page and install it.
Below are screen shots of the relay rule on the Exchange server for this application. Again this was working until the vendor upgraded some software on teh Server. It was working up until a month ago and we havebeenusing Exchange for 1 year.
The vendor statea that the upgtrade has nothing to do with the email function.
