There are some people who would say that, as a server admin, I'm concerned with spam, and anti-spam measures to make my life easier because less spam means less hassle from clients... but I couldn't possibly comment

With my tongue firmly in my cheek I could suggest that was true but, at the end of the day, it's all about customer service - I loathe being swamped by spam as much as everyone and if there is something that I can do to try and reduce that for everyone on my servers. It's a win-win-win-win situation; my clients get less spam so I get less exasperated support tickets, I also see less spam in my own mailboxes so we should all be all-round happy bunnies

Ah, but there's more, and you're right it's not as simple as that...

Follow up:

Yes, unfortunately there is no way to stop all spam, all you can do is try and keep the amount you have to deal with as low as possible.

As a server admin, I can do my best to give you the tools you need to control spam on your e-mail account - and that's the point that most people just aren't sure about.

It is true that straight out-of-the-box anti-spam measures on your e-mail account should have some effect but, to get it working more effectively you then you have to put some effort in to check for false-positives, make sure that your whitelists do what you want.

SpamAssassin

SpamAssassin is the anti-spam system that most people have at least heard of but it is difficult to get working correctly, unless you know your way around it. More for a problem, from a server admin's point of view, is that it is a "resource hog" - it absolutely chews up RAM and CPU time.

Don't get me wrong SpamAssassin is very good at what it does but if I was to choose I'd look elsewhere

In With The New

So, I've done a lot of research and elected to install what looks to be a very user-friendly and quite effective anti-spam handling software.

What's it called?

Sorry but you'll have to wait for that
