Ham spam error

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?

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 help me ???

I have virtualmin pro

Howdy,

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

-Eric

directly from the Virtualmin, namely usermin

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

[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 .. -rw------- 1 ronald.domain-int domain-int 18 may 14 12:04 bayes.mutex -rw------- 1 ronald.domain-int domain-int 12288 may 14 12:04 bayes_seen -rw------- 1 ronald.domain-int domain-int 339968 may 14 12:04 bayes_toks [root@hosting ~]#

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
