in our company we've got some trouble... we got a new firewall, but OTRS was not added as a trusted sender, so all outgoing OTRS-mails that were created within the last few weeks were refused without notification. We now need to resend all mails that were supposed to be sent within the last few weeks.
We also need to inform all ticket-creators that we had technical difficulties sending mails. Is there any handy way to get a per-queue-list of the email-addresses of the ticket-creators? [EDIT: This part is solved, we can do it with the summarize-option and add a reply]
I would appreciate any attempt to help us solving this situation

Best regards
Yasamb
PS: OTRS Version is 3.1.8
