My policy is that if the email is legitimate and is well meant, I will reply in some fashion.
…and how do you know if it is legitimate & well meant?
I’m just saying, the best scam e-mails are the ones that sound legitimate & well meant and the worst thing you can do is to reply to those.
I’m a doctor. Thats my policy.
I fail to see why someone would listen to a doctor for halachic & online advice.
