Is it a newly registered domain, or a new sub domain? New domains are frequently blocked just for being new. Normally I'd recommend 30-90 days of ownership before trying to use it for anything email related. Also ensure that is has a valid A record, or redirects to the mail web page. Sometimes you just need to wait it out.
New subdomains shouldn't have this issue, unless it is not properly authenticated? ~ Matt On Wed, Sep 25, 2024 at 2:05 PM Scott Q. via mailop <mailop@mailop.org> wrote: > Hello list, > > this customer just created his domain, literally yesterday, they are > legitimate and are trying to e-mail some recipient that uses Cisco Talos > protection. > The message is bounced with an error saying it's due to the poor > reputation of a domain used in the transfer but the Cisco Talos website > shows reputation: Unknown > > Could it be something else blocking it ? > > Thanks, > Scott > _______________________________________________ > mailop mailing list > mailop@mailop.org > https://list.mailop.org/listinfo/mailop >
