Gears Posted May 1, 2008 Share Posted May 1, 2008 Hi, Here is the scenario: A spammer sends an email in, then whmcs sends the "received ticket email" back to the spammer. The spammer's address no longer exists, so we get a reply from root@server.domain.com (the mailer daemon) stating that the address no longer exists. Because we get this reply from root@server.domain.com, a new ticket is opened, and because a new ticket is opened, whmcs sends the "received ticket email" to root@server.domain.com. Then this continues back and forth between the mailer daemon... about 15 or so tickets are opened just because we received an email from a spammer and the spammer's address no longer exists. Anyone know how to prevent this? Is it even possible to prevent? 0 Quote Link to comment Share on other sites More sharing options...
WHMCS CEO Matt Posted May 1, 2008 WHMCS CEO Share Posted May 1, 2008 WHMCS already has the built in protection to stop after 10 emails are received from the same email address within 15 minutes of each other - which is why it ended and didn't continue on forever. Any more strict than that and it could start blocking genuine emails from clients. Matt 0 Quote Link to comment Share on other sites More sharing options...
Gears Posted May 1, 2008 Author Share Posted May 1, 2008 So if the protection was not built-in, then the emails could have been going on for a long time! Thanks Matt, makes sense. 0 Quote Link to comment Share on other sites More sharing options...
