Mail is often coming back as not deliverable.

Hi @GeeEyeDi, Thanks for reaching out to AT&T Community and Forums. We understand the gravity of your concern and let us get the help you need.

You can try troubleshooting your email account, settings, and apps by the below steps mentioned;

AT&T Mail account and settings

• Check your email size. If your email is too big, it may not be sent.
• Be sure you’re using the correct recipient email address. If not, you may get error messages like Failed Delivery or Problem Found - Message Not Sent.
• Try signing out of your email account and signing back in.
• Check your spam folder for missing emails.
• Review your settings. Select the gear icon, then check:
  • Blocked addresses: Be sure you aren’t blocking addresses you want to get email from.
  • Filters: Are emails going to the correct folder?
• Check if your account has been hacked. Your account may be compromised if you’re:
  • Missing emails
  • Receiving emails from your own email address
  • Getting complaints about spam coming from your email address
  • Seeing a display name that's different from the one you set up

You can also consult our Resolve Email Issues support article.

Let us know if this helps!

Thank you,

Thank you - I indeed have the correct email address & I have done all of the above unsuccessfully to rectify the issue.

BTW, the article link "Resolve Email Issues" doesn't work.

Hi @GeeEyeDi,

We understand that your emails are not getting delivered. We're here to help you receive your emails to your account.

First, are you using Currently to access and send emails? This is our official webpage that we support for emails.

If you are using a third party client such as Apple Mail or Outlook, confirm that your server settings are correct. If these are incorrect, it can cause issue with sending and receiving emails such as the one you are experiencing.

We recommend verifying that your inbound and outbound server information is correct.

You can reference this table if needed:

While you give that information a glance, can you also let us know if this happens with multiple recipients or just one or two specifically. This can help us identify if it's just a communication issue with the recipients server or something larger.

If you need help with anything else, let us know. We'll be happy to assist you.

Thank you for reaching out to us on AT&T Community Forums. 

Jennifer, AT&T Community Specialist.
