Hi all !!
I've got a Centos 5.11 public mail server running Virtualmin GPL 4.15. I think there a problem in antispam services.
I'm running spamassassin 3.3.1.
Unfortunately I'm not able to attach to this post my configuration files. How can I do it?
Problem is that some customers report me some emails don't arrive to their mailbox so I check my log and see that emails is signed as SPAM and deleted.
Seems that spamassassin is too aggressive but I see a problem in autowhitelist files, I don't know if this issue can create some problems.
All autowhitelist files that are present into homes directories are update at 2012 and a lot of users haven't this file into its folder, seems to be new users created after 2012.
Also, if I create a new mail, the first sender that write an email to that address receive this error but messagge is deliver correctly to the mailbox:
procmail: Enforcing stricter permissions on "/var/mail/USER_DOMAIN.it"
procmail: Error while writing to "/var/log/procmail.log"
Failed to open /etc/webmin/miniserv.conf : Permission denied at /etc/webmin/virtual-server/lookup-domain.pl line 9.
procmail: Program failure (13) of "/etc/webmin/virtual-server/lookup-domain.pl"

I hope this information are enough.
Thanks a lot.
