Even though I still don't understand why the sendmail session I
described isn't "mail submitted via SMTP", I tried a different method of
testing. Using telnet.
Following this,
Using Telnet to send mail by SMTP
http://arnab.org/notes/using-telnet-to-send-mail-by-smtp
"... So now we can send email using SMTP, (and recieve
using POP) all without the use of a mail client or a web
browser."
With Postfix still configured at the reinjection listener with,
127.0.0.1:10026 inet n - n - -
smtpd
...
-o
smtpd_sender_restrictions=check_recipient_access,hash:/etc/postfix/spamtrap
...
and
cat /etc/postfix/spamtrap
[email protected]
postmap /etc/postfix/spamtrap
I initiate the telnet session from my desktop to the server,
telnet 192.168.1.10 25
Trying 192.168.1.10...
Connected to 192.168.1.10.

IIUC, that's a legitimate SMTP session, and that's "mail submitted via
SMTP", no?
Still, no hash-table smaptrap check & detection.
Logs for this session are,
