Email productivity is a hot topic and several companies will launch new products including IBM with IBM Verse.
But do not forget: Good spam protection is a important piece.
Several months ago, in our company, i setup Lotus Protector for Mail Security.
Before the setup, on mornings, we have a lot of spam and undesired messages do deal with.
We loose lots of hours / month just cleaning the inbox.
Some important messages was deleted during this clean process.
Using traveler on mornings was a nightmare.
The life after Protector is very different, there is no inbox cleaning anymore and blocked messages is managed by the users using IBM Notes integrated with Protector
Almost 90% of the hits are blocked, thousand of messages are blocked every day with zero false positive
