Hi Everyone
We are currently using the Roundcube system through a hosting company based in the UK. We have an issue with one of our clients receiving alot of spam emails daily. At present, you have to copy each individual email address from Roundcube, and then paste this into a blacklist within Plesk to educate the spam filtering system for future or similar emails - which is crazy, as you cannot expect a client to perform this task on every single spam email which comes through.
We have read online there is a spam filtering plugin for Roundcube which simplifies this process, but unfortunately this isn't installed and our hosting company have informed us this is the latest version, and there is no other solution available.
We are just looking for some support or advice, if someone could give us some assistance.
