+
+## Name
+
+ec_spool_check — verify spool directory integrity (read-only scan)
+
+## Synopsis
+
+`/opt/msys/ecelerity/bin/ec_spool_check` [ **-c** *`conffile`* ] [ **-e** *`extdir`* ] [ **-x** ] *`spool-directory`*
+
+## Description
+
+**ec_spool_check** walks the message queue under *`spool-directory`* and uses the same spool APIs as the MTA to load metadata and bodies for each message. It prints a summary on standard output (counts scanned, valid, failures). Problems are reported on standard error as lines of the form `FAIL <mid>: <reason>`.
+
+Use this utility to audit an on-disk spool after incidents, partial failures, or upgrades, without driving traffic through Momentum.
+
+### Concurrency and locking
+
+Do **not** run **ec_spool_check** at the same time as **ecelerity** on the **same** spool directory. The tool acquires the spool lock while it runs; concurrent access with a live MTA can interfere with normal delivery.
+
+### Options
+
+<dl class="variablelist">
+
+<dt>**-c** *`conffile`*</dt>
+
+<dd>
+
+Optional path to a Momentum configuration file. If omitted, **ec_spool_check** locates `ecelerity.conf` (or the product-specific `.conf` name) using the same search rules as Momentum (`EC_CONF_SEARCH_PATH` and default install paths). If **-c** is given with a relative path, it is resolved from the current working directory, consistent with other utilities.
+
+</dd>
+
+<dt>**-e** *`extdir`*</dt>
+
+<dd>
+
+Module search path (extensions directory), equivalent to other **ec_** tools that accept **-e**.
+
+</dd>
+
+<dt>**-x**</dt>
+
+<dd>
+
+After the summary, print the oldest and newest verified messages’ metadata **creation_time** (evaluated with the local clock). If the spool is empty, prints `(none)` for those lines.
+
+</dd>
+
+<dt>**-h**</dt>
+
+<dd>
+
+Print usage and exit successfully.
+
+</dd>
+
+</dl>
+
+### Exit status
+
+| Code | Meaning |
+| --- | --- |
+| 0 | No integrity failures reported for scanned messages |
+| 1 | One or more failures (meta, body, or orphan markers) |
+| 2 | Fatal error (configuration, lock, or scan abort) |
+
+### Spool_Backup side effect
+
+If **Spool_Backup** is configured and a small-message body file’s size does not match its metadata, the spool layer may move both files into **Spool_Backup** during swap-in—the same behavior as the MTA. Other operations performed by **ec_spool_check** are read-only.
+
+## Example
+
+```
+shell> /opt/msys/ecelerity/bin/ec_spool_check -c /opt/msys/ecelerity/etc/ecelerity.conf /var/spool/ecelerity/maildir
+Total scanned:    42
+Total ok:         42
+Meta failures:    0
+Body failures:    0
+Orphan L-markers: 0
+```
+
+With **-x**, additional lines list oldest and newest message identifiers and creation times when present.
