[syslog-ng]Doubt !!

[Kleyson Rios]

The expression :

log { source(src); filter(f_mail); filter(f_info);
destination(mailinfo); };

write for destination(mailinfo) the messages where " filter(f_mail) AND
filter(f_info) " is true
or " filter(f_mail) OR filter(f_info) " is true ?

Because in my syslog-ng.conf  I  have :

destination mailinfo { file("/var/log/syslog-ng/gandalf/mail.info"); };
destination mailwarn { file("/var/log/syslog-ng/gandalf/mail.warn"); };

filter f_mail { facility(mail); };
filter f_info { level(info); };
filter f_warn { level(warn); };

log { source(src); filter(f_mail); filter(f_info);
destination(mailinfo); };
log { source(src); filter(f_mail); filter(f_warn);
destination(mailwarn); };

and my logs "mailinfo" and "mailwarn"  are same .
