Why Your BellSouth Email Logs In But Won’t Send

So, your BellSouth email lets you log in, but it won't send emails. Usually, this means your ** settings for getting mail are fine**. But the settings for sending mail (SMTP) are either blocked or not checking out correctly.

Since AT&T manages BellSouth email now, security's tighter. You might get into your account, but outgoing messages get stopped if AT&T can't check your email app the right way.

Main Reasons Why This Happens

• Wrong SMTP server or port is used

• Sending mail without login verification is on

• Not using a Secure Mail Key

• Your firewall or antivirus is blocking SMTP

• Your email app still has your old password

This is a settings mix-up—not an account issue.

Common Signs You've Got This Issue

You might see:

• Emails stuck in your Outbox

• Error messages like “Can’t send mail”

• Logging in on the website works, but not on apps

• No error, but emails never leave the Outbox

• It works on one device, but not another

These signs confirm the problem is with your outgoing mail settings, not your login details.

How to Fix BellSouth Email If It Won’t Send

Make Sure Your SMTP Server Settings Are Correct (THE KEY FIX)

Double-check your outgoing server settings to see if they match exactly:

Setting                                        Value

SMTP Server                          smtp.mail.att.net

Port                                         465 (SSL) or 587 (TLS)

Encryption                              SSL / TLS

Authentication                        Required

Username                              Your full BellSouth email address

Password                               Secure Mail Key

⚠️ If login verification is OFF, BellSouth/AT&T will stop outgoing emails right away.

Change Your Password to a Secure Mail Key

AT&T wants you to use a Secure Mail Key for other email apps, like:

• Outlook

• Apple Mail

• iPhone & Android Mail apps

Even if you can log in, AT&T might block sending if you don't have a Secure Mail Key.

Here's the fix:

1. Log in to your AT&T account

2. Make a Secure Mail Key

3. Use this Secure Mail Key instead of your email password

4. Save the changes and restart your email app
