I have recently converted from Windows to Apple. On Windows, I used a system called CA-Antispam which worked as follows.
You installed the program
You pointed it towards your mail folders containing clean mail
It then built a whitelist of e-mail addresses you received mail from
You then pointed it towards your sent items folders
It then built a whitelist of e-mail addresses you sent mail to
And that was it. Nothing clever, just spam filtering based on whitelists. Anything that came in that wasn’t in the whitelist it marked as Spam. You then went into the spam folder, put a checkbox next to all the mail you wanted and it then moved them back into their respective folders, and then added the email addresses to the whitelist.
Any e-mails you sent, the To: address was also automagically added to the whitelist.
Does this program do this? If so, i’ll happily spend the 30 bucks.
I have personal antispam x5 at the minute, but it’s not quite what I want.
