Apple mail server rejected address

The frustration of an email being rejected by an Apple Mail server!

When an email is rejected by an Apple Mail server, it's usually due to a technical issue or a configuration problem. Here are some common reasons and solutions to help you troubleshoot the issue:

  1. Invalid email address: Double-check that the email address you're trying to send to is correct and valid. Make sure it's not a typo or a non-existent email address.
  2. Domain name issues: Ensure that the domain name of the email address is correctly configured and resolves to the correct IP address. You can check this using a tool like DNSChecker or WhatsMyDNS.
  3. SPF (Sender Policy Framework) issues: Apple Mail servers may reject emails that don't comply with SPF policies. Check your domain's SPF record and ensure it's correctly configured. You can use a tool like SPF Checker to verify.
  4. DKIM (DomainKeys Identified Mail) issues: Similar to SPF, Apple Mail servers may reject emails that don't comply with DKIM policies. Check your domain's DKIM record and ensure it's correctly configured. You can use a tool like DKIM Checker to verify.
  5. Authentication issues: Apple Mail servers may reject emails that don't authenticate properly. Check your email client's authentication settings and ensure they're correctly configured.
  6. Rate limiting: Apple Mail servers may reject emails if you're sending too many emails in a short period. Check your email client's sending rate and ensure it's within the recommended limits.
  7. Blacklisting: Apple Mail servers may reject emails if your IP address or domain is blacklisted. Check your IP address and domain against blacklists like Spamhaus or SORBS.
  8. Email client configuration issues: Check your email client's configuration settings and ensure they're correctly set up. Make sure you're using the correct SMTP server settings and authentication credentials.

To troubleshoot the issue, you can try the following:

  1. Check your email client's error logs for more information about the rejection.
  2. Try sending the email again after a short period to see if the issue persists.
  3. Contact your email provider or IT administrator for assistance with configuring your email client or domain.
  4. Use a tool like Mail Tester or Email Validator to test your email and identify potential issues.
