+## Name
+
+ec_mta_sts_purge — Remove expired MTA-STS policies from the file system.
+
+## Synopsis
+
+`/opt/msys/ecelerity/bin/ec_mta_sts_purge` [ -dir *`directory`* ]
+
+`/opt/msys/ecelerity/bin/ec_mta_sts_purge` [ -dryrun ]
+
+`/opt/msys/ecelerity/bin/ec_mta_sts_purge` [ -v | -verbose ]
+
+## Description
+
+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 HTTPS. 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.
+
+### Note
+
+The **ec_mta_sts_purge** script will delete files in the default location. If you have specified a different location via `mta_sts_policy_store`, the `-dir` option must be used.
+
+The following options change the behavior of the **ec_mta_sts_purge** command:
+
+<dl class="variablelist">
+
+<dt>-dir directory</dt>
+
+<dd>
+
+Specify the full path to the directory where the policy files are stored. Default is `/var/spool/ecelerity/mtasts`.
+
+</dd>
+
+<dt>-dryrun</dt>
+
+<dd>
+
+If this option is specified, the script will just list the files that would be deleted.
+
+</dd>
+
+</dl>
+
+The following is an example:
+
+```sh
+/opt/msys/ecelerity/bin/ec_mta_sts_purge -dryrun -dir /path/to/policy/files
+```
