AreaFix

AreaFix is the FTN netmail robot used to manage echomail subscriptions. A linked system sends netmail to AreaFix at the board's FTN address, with the link password in the subject line and commands in the message body.

OxideBBS includes the pure oxidebbs-ftn command parser, inbound tosser processing for netmail addressed to AreaFix or AreaMgr, and a local sysop-side executor:

oxidebbs-server net areafix send <link> "<commands>" --password <password> [--network <network>]

The executor authenticates the supplied password against the configured link password, applies subscription commands to DecentDB, audits the activity, queues an AreaFix reply as outbound netmail, prints the reply text, and queues targeted per-area/per-link rescans for +AREA.TAG ! commands. Inbound AreaFix netmail uses the same processor and queues reply netmail plus rescan requests during net toss.

The parser recognizes every supported command form and normalizes area tags to uppercase ASCII.

Supported commands:

Command	Meaning
%LIST	Request a list of available areas.
%QUERY	Request the areas currently subscribed for the link.
%HELP	Request command help.
+AREA.TAG	Subscribe to an area.
-AREA.TAG	Unsubscribe from an area.
+AREA.TAG !	Subscribe and request a rescan.

Command keywords are case-insensitive. Area tags may contain ASCII letters, digits, ., _, and -; parsed tags are normalized to uppercase.

Example body:

+FSX_GEN
+RETRO.BBS !
%QUERY

Runtime behavior:

• inbound AreaFix netmail is authenticated against the configured link password
• %LIST, %QUERY, %HELP, subscribe, unsubscribe, and rescan commands are audited
• generated replies are queued as pending outbound netmail packets and are materialized by net scan
• +AREA.TAG ! creates a pending network_rescan_queue row for that link and area
• net rescan list/process/cancel lets the sysop inspect, process, or cancel queued rescans
• manual net areas subscribe and net areas unsubscribe remain available for direct operator-side subscription changes
