Netmail

FidoNet point-to-point mail — like email, but routed over BinkP
through the FidoNet/fsxNet/etc. network instead of SMTP.

How it differs from Echomail

Composing

/netmail/compose (web) — picks recipient by node address + name.
The compose form supports markdown for the body and adds a kludge
line (@MSGID:, @INTL, @TZUTC) automatically.

Inbox

/netmail/. Unread netmail shows in the badge in the nav.

AreaFix

AreaFix@<your-node> is a virtual recipient that lets other
sysops subscribe to your areas without bothering you. Which areas a
downstream node can see is controlled by that node's echo-area
subscriptions on its network record (Admin → Echomail → Hub), not a
separate allow-list page. To see incoming AreaFix requests and how
they were handled, check the AreaFix Log at
/admin/echomail/areafix_log.

FileFix (FileFix@<your-node>, also File Fix/FileMgr) is the
file-echo counterpart — same idea, same password (Subject-line,
FTS-0024), same +TAG/-TAG/+ALL/-ALL/%LIST/%HELP grammar,
but for file-area subscriptions instead of message areas. It shares
the AreaFix Log page above (a Bot column and filter distinguish
AreaFix from FileFix rows), rather than having a separate log.

Encryption

Bare FidoNet netmail is not encrypted. For secrets, encrypt the
body yourself (PGP, age) — the network treats it as opaque.
