SPAM is a constant problem everyone faces with email. It's been reported that over 84% of all email is spam. By following the steps below you should be able to reduce most of the potential spam from hitting your mail boxes on a SmarterMail VPS.

Minimum Password Length - Set this to at least 8.  Higher if possible, but no less than 8.  
Require a number in the password

Require a lower case letter in the password
Require a symbol in the password
Require password does not match username
Disable password strength for existing passwords

Block Period - 3 minutes seems to work well.

Security > Antispam Administration > Options

Leave the rest of the fields Unchecked

Incoming Weight Threshold - 30 and Checked/Enabled
Greylist Weight Threshold - Make sure this is NOT enabled, so that all email is Greylisted
