Bgpenalty Option

From Messaging Server Technical Reference Wiki
Jump to: navigation, search


When an authentication failure occurs from a particular client IP address, subsequent authentication attempts from that IP address are treated as "BadGuys" and are delayed. If an authentication failure is followed by a successful authentication, the successful authentication is delayed, but the IP address ceases to be treated as a "BadGuy" for subsequent attempts.

The bgpenalty option (available under base, imap, pop, mmp, imapproxy, and popproxy) specifies the length of time in seconds added to the authentication delay after each failed authentication.


The default value is: 2
