>> Any suggestion? > > Implement rate-limiting at the MTA layer.
While rate limiting in the MTA is the better solution, you can also rate limit in SquirrelMail by using the Restrict Senders plugin. That plugin (as well as Squirrel Logger) can also be configured to send you alert emails so you know when an attack is taking place. -- Paul Lesniewski SquirrelMail Team Please support Open Source Software by donating to SquirrelMail! http://squirrelmail.org/donate_paul_lesniewski.php ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
