Hi all,
i have a mail mail1@domail1.com on domain domain1.com with a forward rule on mail2@domain2.com on domain2.com. The 2 mail are on different azure ad tenant.
The second mail is managed by me, it is the only mail with licence to receive mail(this solution is temporary). My problem is that all sent to mail1@domail1.com and after that forwarded to mail2@domain2.com finish into spam, eg mail from customer from gmail, live yahoo etc...
On my tenant i have all setting at default, i checked message trace but i got this without information:

i do not understand what is the problem, if is from my side o from the mail that forward the message. There is something else that i can check?
Regards
