The SMTP 5.1.2 error code is received when one of the servers on the way to the destination is unable to resolve the domain name of a recipients email address. Said differently: one of the servers on the way to the destination, including your server or your ISP, has a DNS problem or, possibly correctly, does not like one of the email addresses in the message’s TO, CC and BCC fields. The first you should check all the recipient email addresses for incorrect domain names (misspelt domain names, or maybe, totally non-existent domain names) – remember, error code 5.1.2 is very specifically an error with the domain name of one of the recipient email addresses. If all the recipients email addresses check out as regards the domain part of the email addresses, then one of the servers on the way to the recipient(s) has a DNS problem – usually this will be one of the first 2 servers in the chain, your own mail server (or your network) or your ISP’s mail server. In summary: most SMTP error 5.1.2 conditions are caused by misspellings of the domain name part of a recipient email address. However, with the proliferation of the spam, error 5.1.2 is also often encountered by automatic “out-of-office” replies to junk mail because the domain n

Solution 1: Make sure the recipient's email address is correct This is the most common issue that causes 5.1.x errors. Check for correct spelling. If you change something, send the email again. Solution 2: Remove the recipient's email address from the auto-complete list Remove the recipient’s email address from the list of suggested names in https://support.office.com/en-us/article/Fix-email-delivery-issues-for-error-code-5-1-1-through-5-1-20-in-Office-365-79e91ade-5c83-405b-a37d-d99c7d069b13 the auto-complete list, then type it again before trying to send the email.

If you need more detail about this, see Remove suggested name or email address from the Auto-Complete List in Outlook Web App. Create a new email message. In the To field, start typing the recipient's name or email address until the recipient appears in the drop-down list. Use the Down Arrow and Up Arrow keys to select the recipient, and then press the Delete key. Type the recipient’s complete address and then send your message. Solution 3: Make sure the recipient doesn't have an email message forwarding rule in place Did you send the original message to exactly the same recipient address that is shown in the NDR? You can verify this by comparing the address provided in the NDR with the address shown in the original message that is in your Sent folder. If the addresses don't match, contact the person you sent the original message to and ask them if they have an email rule to forward messages and ask if they know it's working correctly. Their rule could have tried to send a copy of your message to a bad email address. If the person does have such a rule, they will have to either correct the email address or remove the rule in order to prevent NDR 5.1.x
