 The **ec_mta_sts_purge** command is a utility script used to remove expired MTA-STS policies from the file system.
 
-Momentum caches MTA-STS policies on the file system.  This is to reduce how often Momentum needs to fetch the policies using HTTP.  This also prevents a large number of fetches on a restart.  These policies will normally get updated regularly, but if some domains have not been used for a long time, this command can be used to delete the expired policy files for these domains from the file system.
