→LearnAsSpam / LearnAsHam (spam/ham training)
To install:
To install:
* Enable bayes database as described in [[Email#Bayesian_Autolearning | Bayesian Autolearning]] (not the best approach, prefer manual learn by user), or
* Install smeserver-learn as per wiki page [[Learn]](and keep auto-learning off), then
* Instruct your users to move any SPAM they find from their Inbox to their LearnAsSpam folder, and to COPY any non-spam (ham) they find in their junkmail folder into their LearnAsHam folder.
This is a really efficient way to reduce impact of SPAM to your particular installation. Do not fear to run again files that are tagged as SPAM, as they will either get ignored if all their patterns are known, or the Bayes might catch one more pattern that could help you to get ride of the next incoming SPAM to even get accepted.

{{Tip box|Mobile devices have a tendency to frequently disconnect and connect from the network. When this disconnect happens, the sessions on the server are not always immediately cleaned up (they get cleaned up after a time out of some minutes). When the email client reconnects, they create new network connections and you get into the situation that these new connections get denied because of the concurrency limit. On the mobile device this may be noted as a "Unable to connect to server" message.
