Our domain is getting flooded with spam mail. I have been asked to come up with a solution. We have sendmail as our edge transport for mail, it has spam assassin installed but not configured, and I was thinking of trying to configure it.
On the other hand, I have read about a company called 'message labs', that collect all mail, scan for spam and remove it prior to sending it to our domain.
I guess my questions are, is spam assassin a good solution? if so, what documentation is there for its configuration for someone who has never used spam assassin?
What do you guys thinking of the message labs solution? Obviously its a cost to the company, but is it a better solution?
Your advise is greatly appreciated. Thanks.
