Enable Greylisting

Problem reported by Adrian Pope - 9/25/2014 at 10:36 AM

Not A Problem

Due to an increase in the amount of spam we are receiving I went to enable greylisting. From the Security>Greylisting I enabled greylisting for everyone.

It has been a few days now and I went to view the grey list report and it appears the grey list is not gathering any stats (allowed connections, delayed connections, etc) so I am assuming that even though I enabled greylisting... it is not actually running. Does anyone know why this would happen (I did restart all services after enabling greylistings)?

Make sure you have disabled the Greylist Weight Threshold under
Security -> Antispam -> SMTP Blocking

That was it. Thanks for the suggestion.

It doesn't work, I disabled Greylist Weight Threshold but there is no any stats. It seems greylisting doesn't work in v.13

It started working, after SmarterMail restart we have a greylisting stats.

Perhaps a note needs to be included saying a Smartermail Service restart is required?

You should also minimize your greylisting block time.

A block of 1 minute seems to work as effectively as the default of 15 minutes.

Here are the Greylisting settings we use - as stated in my antispam document:

**ChicagoNetTech's Greylisting Settings**

Do NOT allow users to override greylisting. It will only overload your help desk and give you grey hair trying to troubleshoot

PS: I should have a revised version of my antispam document available within the next two weeks.
