    Even if the recipient’s website has been deleted, disabled, or expired, it can no longer be redirected to this mail server.

    2. Invalid MX Records For All Recipient Domains

    If the MX records for the recipient’s domain are configured incorrectly, the sender’s mail server itself will be able to correctly forward messages to the recipient, usually the mail server.

    Any mistake in a particular DNS setting for a recipient’s web address may render it unreachable by one of our other external mail servers.

    If there have been recent changes to the DNS, it will definitely take some time to fix them on the Internet, and the domain may not be routable during that time.

    Some temporary DNS resolution issues with the sender’s ISP cause the recipient range to not resolve properly and fail to redirect web mail to it.

    Messages sent in such cases may be returnedContact the sender with a “550-Unrouteable” error message.

    If you notice any DNS or MX errors, or missing records of problems with web connectivity to the remote mail server, contact the receiving server’s support team at this point as well and fix it.

    3. The Search Found The Sender’s Mail Server To Be Unavailable

    Some delivery servers have strict security settings to prevent spam. One such comparative security measure is to search the sender’s public domain.

    If the sender’s email device is on the spam blacklist, almost all recipients will reject emails from that element. Some even accept mail only from greylisted senders.

    RDNS is also One home monitoring check, which must match the IP address and hostname of the mail server. A special PTR record is designed to redirect IP addresses to the sender’s server name.

    Many servers reject emails from IP addresses whose PTR record may not match the sender’s address. If the Snail mail server were to reject emails because it couldn’t properly verify the sender, it would reject most emails.
