The system that sent the message 1:226/20 didnt include an origin line, however did include a MSGID with the AKA.

When sbbsecho processes this message for a system not in zone 1, the message is imported as coming from that (imported) system's zone. (The example below, the message was imported by a zone 3 node).

2026-02-11 08:25:09 Added BBS_ADS message from Petar Smilajkov (3:226/20) to packets for 0 links (exceptions: 1 seen)
2026-02-11 08:25:09 BBS_ADS: Imported message from Petar Smilajkov (3:226/20) to All, subject: [ANSI] Silfen Path BBS

(And as per #828 the seenby lines werent imported either.)

Thus when reading the message, it looks like node 3:226/20 sent it, and if you were to reply via netmail to the node, the pre-filled destination address is incorrect.
