Hello I'm new to the forum and I hope to get some help. In the last couple of day I have had some problems with spam being sent from my server. I believe the problem it originates from a joomla site or a custom made php site, I know the problem isn't ISPconfig. My question is this: Can I blacklist all emails going out of the server which doesn't match any domain name under "Clients"? All the mail are being "spoofed" as yahoo, drug sites and gambling sites. I know isn't a viable fix, but I hope it can buy me some time. I have played arround with "Email -> Global Filters -> Postfix Blacklist" but without luck. Another question... Is it possibale to get an email when the server is overloaded? Furthermore... I will happily accept any advice/tips/suggestions.
You can use munin for this. in munin.conf Code: contacts email contact.email.command mail -s "ACHTUNG! MUNIN-Alarm fuer ${var:group} :: ${var:host}" [email protected] contact.email.always_send warning critical # a simple host tree [yourdomain.de] address 127.0.0.1 use_node_name yes postfix_mailqueue.active.warning 30 postfix_mailqueue.active.critical 50 postfix_mailqueue.deferred.warning 15 postfix_mailqueue.deferred.critical 50 postfix_mailqueue.incoming.warning 25 postfix_mailqueue.incoming.critical 35
