Yesterday my software diverted an email into my spam box - nothing unusual about that as it happens several times a day. However it seemed at a quick glance to be a genuine request for help on a family history problem (surname may have been CHILD). So I clicked on the "not spam" button and it vanished - and I can't find it anywhere on my computer or on the server. So apologies, whoever you, were but I am not able to reply.
This may also be a good time to remind you that if you send me an emailed request and want a reply make sure that your system will accept my reply. So systems seem to be set up to treat as spam anything they don't recognize and I know at least one recent message I sent didn't get to the questioner for this reason.
