It's not about stopping SPAM it's about managing you mail box.

So people are using "Block this sender" for real people?
If I put a co-worker on the block sender list they would just come to my desk and ask me if I got their email...

Can you please share how you are managing your mail box with the block sender "feature"?

I use this to block spam addresses. Like all other menu items, an option to hide it would be find with me, but do not remove the feature.

I am not sure this is the best place to carry on this type of discussion, but maybe it is.
At any rate, how effective can blocking a sender be to block spam addresses. With today's spam bots, the "sender" is always changing.

I cannot imagine this is doing anything more that introducing overhead on the mail files.

I would agree that it does create overhead but again the tool was ment to be a tool. If the user misuse it then you need to take them to task. You asking to remove this is like asking to take out Rules because the made one to delete all of the mail you send them. It's tool and abused it does become a problem. If they use it properly it can help manage the mail box.

^Lol! Seen that one too!

I agree that it is useless. Spam sender names are always changing. If you have a user who does use this feature, his efford is actually wasted. It would be much better instead if he would forward the message to a central SPAM database, where an admin can analyse it and improve the overall SPAM filters.

If it is not removed it would be fine if it could be hidden via policies.

The real point of "Block this sender" and equivalents in other mail programs is to give the user a feeling that they have _some_ power over spam, giving them something else they can do besides complain to the help desk! It's purely psychological.

For the messages that break-through...it was effective in stopping perpetual spam that my SPAM filter blocked...like 25 of the same subject from 25 different people... I view it as a compliment to the primary filter. It should not be viewed as a company's spam solution.

I need to demote it too... I really like and use this feature... also my agents. But I agree that in some environments it is a good idea to hide it... Maybe via Mail Policy?
