sa-learn... when mail is moved to "Junk"

[vsnap]

Hello,

I think it would be pretty usefull if Roundcube would trigger a "sa-learn..." command when a mail is moved to the "junk" folder. Due to that the spam mail would be learned by spamassassin and woul help to improve the filters. Or is there already a similiar Feature comming (couldn't find anything, yet).

Regards,

Except not all servers have spam-assassin installed. As such, RoundCube won't code toward a one server setup over another.

You could write a plugin to do this. Once RC matures, and a real plugin structure is available, I'm sure this and many other plugins will be available for things such as this.

I actually think that quite some RC installations have SA and spam is becoming (actually already is) a nuisance.

@vsnap. I would be happy to learn how this works. maybe you can show the basic code structure to mkae this happen?

I think we would need.
- a config option to override and turn on/off
- a check in PHP code to see if SA is installed and turned on
- the sa-learn command to add it to the learning base

I'm sure many people do this already. It is, in my opinion, not the job of a webmail interface to do this. It is however not a difficult script, put into cron.hourly which simply reads the mail from Junk, runs sa-learn and clears the mailbox.

Pretty much exactly what I have, except every 15 mins, not to mention I wouldn't want this system wide in any case because users often don't classify spam properly and if you have a system wide rather then per user setup, this can cause more headaches then its worth. Also I teach spamassassin about ham, both to cover false positives and to increase the effectiveness of spamassassin, and then I dump the mail to a diff folder, although you could just delete the messages entirely I suppose.

hope this can help anyone

where i should put coding above on roundcube

[xray]

You should run this script from/with cron daemon periodically. These scripts are shell scripts. Example run this script every 30 minutes. This means when a user put an e-mail into ".Spam" or ".Junk" folder spamassassin will learn them, but it will not delete these messages after they are examined.

PS. Sorry for my english, but I'm hungarian

[AlexRezid]

As said, just create another folder (MissedSpam) and put missed spam in it. Then, run sa-learn on it every hour/day/... and deleting mails after job.
