I am by no means an expert at e-mail. But, my first guess would be that
the server at polluce.unimo.it did a test of the recipient of the e-mail.
It connected, tested the recipient e-mail address, and then disconnected.
That's exactly right. The receiving system performed sender address
verification.
Question: can you tell from the logs whether the SAV system
QUIT or simply disconnects. I currently track failure to
use quit (via assp front end) as a factor when deciding
which IPs to blacklist.
