We are testing on ELGG2.2.3 at the moment.
We use the Groups and Group Tools plugin. We tested the Group Export feature successfully whereby we as Group owners / admins can export a list of group members directly to CSV - no problems here.
However - I tried to send a group email from the group, and even though the feature is set to allow this in the settings, and the button and screen works, I can create the email on the page etc, when I click the Send button, nobody receives the email.
And to top it all, the Statistic for Group Emails Sent count in the Statistics Dashboard increases by one, recording that a Group Email has been sent.
But nobody receives an email.
Other email features are working. Like when I post a discussion, and someone Likes it, or replies to it, I get an email notification. But no Group Email goes out.
Where do I begin to debug what the problem might be?
Security issues should be reported to firstname.lastname@example.org!
