mail1.mailcorvid.com

This host sends bulk email from 158.69.49.215 on behalf of the operator of mailcorvid.com. Mail from it is signed with DKIM, authorised by SPF, and carries a one-click unsubscribe header and a postal address.

If you did not ask for this mail, it should not have been sent. Every message carries a working List-Unsubscribe header, and mailing abuse@mailcorvid.com will exclude your entire domain from every future send. Both are honoured within minutes, not on a schedule.

Contact

Both addresses are monitored and answered by a person:

To have this IP stop mailing your users entirely, mail abuse@mailcorvid.com with the domains concerned and they will be excluded from every campaign, existing and future. Mail to abuse@mail1.mailcorvid.com reaches the same place.
