Yes, indeed SElinux is disabled.
By the way, I tried this on /etc/MailScanner/MailScanner.conf
Run As User = postfix
Run As Group = postfix
Incoming Work User =
Incoming Work Group = clamav
Quarantine User = root
Quarantine Group = apache
SpamAssassin User State Dir = /var/spool/MailScanner/spamassassin
Quarantine Permissions = 0660
Incoming Work Permissions = 0640
Rebuild Bayes Every = 0
Wait During Bayes Rebuild = no
And this is what I done on /etc/MailScanner/spam.assassin.prefs.conf:
# bayes_auto_learn 0
The error still continues. Because I am running out of resources I am ready to investigate the VMWARE image available.
Any other suggestions ?
