Couldn't you ask for the email header from one of the people who complained?

Oh :-( Does anyone know someone who could help?
(I guess you've already checked that the server actually sent those, and that it wasn't just in the emails' 'From' field? - Sorry, that's the only thing I know about this..., there are people doing that with our private server, too. I think there is an option in the mail server settings that allows other email programs to request confirmation that the mail was actually sent from that server).
Hi Maren,
I suspect the emails weren't sent from our system, as the email addresses that replied don't appear in our mail logs.
But I'm being cautious because the system isn't as secure as it could be with an expert in the helm.
