One of our clients has 4 Top Level Domains since they merged companies.
User A from TLD 1 has been authorized to send e-mails on behalf of a mailbox on TLD 2, DMARC is in place on all TLD’s and all e-mails sent by user A from TLD1 on behalf of the mailbox on TLD2 bounce.
On the page “https://dmarcian.com/how-to-send-dmarc-compliant-email-on-behalf-of-others/” it states that sending mail on behalf of subdomains is possible however, I can’t seem to find out wether or not it is possible to configure DMARC in a way where it is possible to send on behalf of another TLD’s mailaddress.
Anyone here with experience or advice on this?
thanks for the help!
