We have Gemini 2.1.1.

In past we used our MS Exchange Server 2003 to send mail alerts.

We were able to send mails to external mail adresses (e.g. to every customer/supplier).

Suddenly, we are no more able to send mails to external mail addresses. Sending to our internal mail adresses still works.

The change in between, was an upgrade from MS Exchange Server 2003 to MS Exchange Server 2007. Our IT rechecked all settings and gave full access to ITS to use sending mails. They do not have any further idea how to fix this major problem.

When I add a comment for example into an issue, and it has an internal and external set as Issue watcher. The mail I receive just has the internal mail adress in its recipients list, the external mail address is not visible in the recipients list.

 

This is the err log I receive just after commiting the comment.
