Will sign up SpamHaus Professional improve EFA?
Posted: 12 Feb 2016 00:25
Hi All,
I received this email as below. Is it a spam?
Before deciding to sign up commercial backend (appear to have many things to setup) I need to know if my EFA installation is using SpamHaus. In my postfix main.cf, I am not using SpamHaus. Mine is this,
In fact I tried not to use barracudacentral also but the amount of spam bots and attempt is astonishing! So at least that reduce some loads. Personally, I think SpamHaus has a lot of false positives...
However in spam.lists.conf file I see the definition of SpamHaus. But it is only a definition. My MailScanner.conf is not enabled to use it,
Anyone got good comments about making EFA more accurate (if you think it is not) by using those commercial service (will it)? Or just buy their box/solution (defeat the purpose of deploying EFA in the first place).
Thanks.
