The issue has been solved.
I'm not sure if someone read my first e-mail and silently operates to
verify/solve without reply (google style) or if it's a natural update
over a false positive or even if the recipient comply with them as a
customer.
I would like just to puntualize I'm not sure I was writing to the right
address.
For sure nobody replied me from postmas...@hostedmail.com (7 days
passed) and no bounce come back.
I don't write to postmas...@tucows.com because I realize it was solved
during the e-mail composition.
About the hostedmail.com domain, I searched a bit before ask here.
The owner/registrant is redacted for privacy.
No web redirect.
No TXT records.
Abuse info was ab...@hostedmail.com ( on abuse.net )
The registrar is Tucows (as thousand of other domains that are not owned
by them).
As a mailbox provider I think they should better identify themself.
About the non cooperation I think that correct sender "pay" for spammer.
Sending promotions to user that subscribe for that or for free services
accepting also ads, is a correct practice but is often misunderstood
(even from recipients) because 98% of the similar traffic is incorrect.
But transactional e-mail should be easier to verify as it's a total
different content.
Thanks for help,
Luca
