gsstore'dan aldığım ürünler için gecikme olanlardan maille bilgi istiyorlar mail atıyorum sanırım gitmiyor sorunu yaşayan var mıdır ?



Delivery has failed to these recipients or groups:

eticaretdestek@gsstore.org
Your message couldn’t be delivered because the address you’re sending to needs to know who you are before it'll let your message through.

To fix this problem, contact the recipient (by phone or instant messaging, for example) and tell them to ask their email admin to configure the recipient’s mailbox to accept messages from you.

For Email Administrators
This error occurs when the recipient's mailbox is configured to reject email from anonymous users. To fix the issue, either add the sender's address to the allow list for the mailbox or turn off the mailbox setting that rejects email from anonymous senders.
