Imack said:
Is there any point to this and if so do I block the sender, or block the
senders domain?
I have already done both to 40 kazillion mails, but the spam keeps
flowing.
There's no point unless it's a recognizable repeat offender who does not
change their email address.
IMHO people get too hot and bothered about spam. Deleting my 500 or more a
day takes me little time, probably because most of the mail from legitimate
senders gets moved to other folders by message rule and each such move has
"and Stop processing more rules" as an action.
