Can't receive email from several servers?
Yesterday I applied for digital receipt from two certain website. Then they sent mails automatically.
However, my mailbox.org account could receive neither of them. So I had to use other email account.
These mails work fine with a dismail.de or protonmail.ch account.
After 24 hours, these mails still remain unseen at my mailbox.org account. not in the trash folder.
I checked, these two senders are: email@example.com and firstname.lastname@example.org
Could you help me with that?
I am afraid of not receiving mails from certain servers, which i am not aware of.
