My pc (or email server A1) appears to try to send out spam emails from email adrresses that are nothing to do with me, and to addresses that I don't know! Norton gives me a warning each time (so hundreds in each time) that blocks my screen, etc.
Norton "E-Mail-Fehler"
How can I stop this spamming activity? (I don't want to deactivate Norton)
I don't find any relevant solution via a Google search (yet), or from Norton.
