We are running LimeSurvey V3.24.2 CE and we want to send emails through a Microsoft Exchange server. The connection is established correctly, authentication succeeds, and the exchange server accepts the email from LimeSurvey.

However, and this is the problem, the server doesn't send the email because the FROM field doesn't match the account used to authenticate. Instead, it appears to use the email of the person owning the survey. Is there a way to change this behavior and set the FROM field to a fixed value, regardless of who owns the survey?

Update: I partially solved this problem by manually changing the admin email in the survey (Survey > General Settings > Administrator email address) to the email of the Exchange server.

Is it possible to change the default value from the creator's email to a static one?

You have to use a plugin or to do what you done …

We have a plugin but only for 4.X … bugs.limesurvey.org/view.php?id=10529

With 3.X : manual.limesurvey.org/BeforeTokenEmail is done for this.
