Hello, i'm afraid with spam, every day the spam is rising and increasingly come more spam, I have enabled spam controls but not enough, what options do you have enabled? Is there any doc which recommend how to improve the detection of spam?

Have you enabling Greylisting? Using greylisting can make a bit difference.

You can enable that in Email Messages -> Email Greylisting.

Another idea is to use DNS blacklists like spamhaus.org in Postfix.

Hello, i'm sorry for my delay in answer :-(

I have enabled greylisting, and one dns blacklist, but i view an error when i report one mail to spam, this is the error:

bayes: expire_old_tokens: locker: safe_lock: cannot create lockfile /var/spool/mqueue/.spamassassin/bayes.mutex: Permission denied plugin: eval failed: bayes: (in learn) locker: safe_lock: cannot create lockfile /var/spool/mqueue/.spamassassin/bayes.mutex: Permission denied ERROR: the Bayes learn function returned an error, please re-run with -D for more information at /usr/bin/sa-learn line 493. Learned tokens from 0 message(s) (1 message(s) examined)

Can you describe how you're reporting the email as spam? For one, what email client are you doing that from?

directly from the Virtualmin, namely usermin

Hmm, what is the output of this command:

ls -la /var/spool/mqueue/.spamassassin/

Wed, 05/14/2014 - 14:31
[root@hosting ~]# ls -la /var/spool/mqueue/.spamassassin/
total 300
drwx------ 2 ronald.domain-int domain-int   4096 may 10 10:49 .
drwxrwxrwx 3 root                mail           4096 may 10 10:49 ..

Hmm, it's possible that ham/spam learning won't work with the particular spam processing mode you're using at the moment.

However, I'm curious whether the user you're having problems with currently is "ronald.domain-int"?

No, this user Ronald it's the only can report spam through usermin, possibly some command I was trying to change permissions to fix this error, but I understand that I have to apply for per-user and it should be fine by default

You can add the settings of the spamassassin rules in Mysql, so the training is easy.

And install the plugin @johndoh http://plugins.roundcube.net/packages/johndoh/

Thankyou bernardo, i try ;-) I hope it's easy install, finally my virtualmin pro with 100 license seem has not sufficient to work with antispam :-(

When in doubt, get someone who knows what he/she is doing. Configuring a server is not rocket science, but it requires that "minimum" amount of knowledge and patience.
