I happen to have a very common name.
I own the corresponding gmail account @gmail.com and I regularly receive emails meant for someone else.
Because they very often seem to contain important information, I always reply to let the senders know that the actual recipient of their emails was not who they wanted.
Some months ago, my company asked all employees to follow an online course on security risks.
The course suggests to never reply to emails sent by someone we do not know.
It seems reasonable as a policy for a company.
I am wondering if this is something I should do even with my personal account with the consequence that probably an honest person will not receive an important information.
