In order to keep my unto.net email address up and running during the move I set the MX records with EasyDNS to redirect everything to my Gmail account.
Gmail does a very good job at catching most spam, and has the best interface I've used so far for quickly removing the spam it doesn't catch. And when you do remove the spam, you seldom see a similar message a second time.
The thing that blew me away is that I have received 4645 spam messages in the past 25 days. That's 186 spam mails a day total to four email addresses that all get collected together. (One, my primary unto.net address, which has been in use for a bit less than 10 years, two, my WSO address, three, an old work address that gets nothing but spam, and four, the Gmail address.) These spam mails amount to some 40MB of wasted bandwidth and storage space (as they are just sitting in the Spam folder on Gmail.)
I've only received 468 personal emails over the same 25 days (averaging 19 a day). So all in all, I've received just a hair under 10 times more spam than I do legitimate emails.
I remember seeing someone estimate that 90% of all email is unsolicited commercial email, scams, or viruses. The past 25 days have confirmed this ratio for me personally. And while the filters are good and all, how long can people tolerate it? Or a better question -- how do people without decent spam filters deal with using email any more?
