Currently with location screening, any countries in the blacklist, the emails are simply dropped. In the main this has worked well with blocking 90% of the countries that we never expect to receive emails from and I think has really helped with malware.

However, once every few months, we miss an email that is sent by a helpdesk system or CRM system which for some reason is located in a country in the blacklist even though the supplier we are dealing with is not located in that country and their usual emails come through another system. I suspect that we are also missing emails that we are not even aware of that we should be receiving, because we are not waiting for that particular email.

I have come to the conclusion that a simple blacklist is not entirely practical because there is no way to track an expected email if it's blocked by country. I always have to keep asking the sender what IP address and country the Mailer program is using/from which is really not a desirable way to manage emails and this is causing frustration for end users.

I would like to request that we have the option to either blacklist a country or filter a country for smtp email connections as there are certain countries where an outright ban is appropriate but other countries where a spam filter approach might be better. In fact what I would do is set all countries to filter and after a couple of years, just block countries where we get no legitimate emails and filter the rest.

In addition, it would allow us to whitelist senders from filtered countries whilst still filtering everything else from that country. Currently I have to allow an entire country even if we only receive one sender from that country. Geolocation is great, but we need to go beyond simply blacklisting countries. I hope my suggestion of blacklisting and filtering lists would solve this.

With regards to my other request about separating authentication block list vs smtp block list - that request is still valid and relevant. We don't need people outside the country logging into the email.

Hopefully this latest feature request can be accommodated as well as separating authentication and smtp block list.

Thank you
