Unable to Relay - sending through smtp from IIS app
Posted on 2010-11-09
Our development group uses jira website and they have setup the smtp to our exchange server. It is able to send emails internally, but when they try to send to an external email address they get the following info in the log...
An error has occurred with sending the test email:
com.atlassian.mail.MailException: javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
com.sun.mail.smtp.SMTPAddressFailedException: 550 5.7.1 Unable to relay
I have tried adding the server IP address to the connector, but it doesn't send out to an external email address. This stopped working once we found out we were an open relay with our default connector and turned that off.
We are using Exchange 2007
