I get too much spam. Specifically, my home account gets close to 500 spam messages a day. Normally, I rely on SpamSieve on my Macbook Pro to filter all that noise, and it does a pretty good job (on average 1 spam a day makes it through). But now that I’m also getting my e-mail on my iPhone, SpamSieve is no longer meeting my needs. Since SpamSieve depends on my Mac to be running, and often the Mac is: off, alseep, or just not on the Internet; all that e-mail has been showing up unfiltered on the iPhone.
So this weekend I’ve moved my spam handling back to the server-side. The first step was to starting removing as many bogus connections as possible. To do that I implemented fake MX records, and SMTP transaction delays. Next I started greylisting (using milter-greylist) all incoming e-mail. You can read more about these spam fighting techniques here
The results over the last 24 hours: approx. 10 spam messages were logged in SpamSieve
I plan to start using SpamAssassin again to handle those few messages that still make it through the new server-side spam tools, but life is now much better on the iPhone.
Hi Sandro,
How effective (in percent) is your greylisting implementation? Do you ever find greylisting delays legitimate messages unnecessarily?
