Was taking a look at this howto and wanted to see if there was anything from the Postfix HotTo that would need to be changed. http://www.howtoforge.com/antispam_smtp_proxy Postfix Howto used: http://www.howtoforge.com/virtual_postfix_mysql_quota_courier I am also using Greylisting to smack the spmmers around a bit. Can anyone tell me if there are any issues that I could possibly run into? From the article it looks like you install and config and off you go. Would like to add this if possible. Would love to add this if it would help beat back the "canned meat by-product" people.
