10 Way to Fix Roadrunner Email Not Receiving Emails

If your Roadrunner email suddenly stops sending or receiving messages, it can disrupt communication and productivity. Most issues are due to simple misconfigurations, server settings, or password problems that you can fix quickly.

This guide helps you diagnose and resolve the most common sending (SMTP) and receiving (IMAP/POP3) issues, so your Roadrunner email works smoothly again. For direct assistance, call 1-877-337-8298.

Quick 5-Minute Diagnosis

Before diving into advanced settings, perform these basic checks:

1. Check Your Internet Connection

Your email client needs a stable connection. Open a website like google.com. If it doesn’t load, restart your modem/router.

2. Verify Roadrunner Server Status

Sometimes the issue is on Roadrunner’s side. Check websites like Down Detector for outages.

3. Log in via Webmail and sign in.

Visit https://webmail.roadrunner.com

If webmail works: The problem is in your email client.

If webmail fails: The issue is likely your password or account status.

4. Fixing “Unable to Send Email” (SMTP Errors)

If you can receive emails but not send them, the issue is almost always your Outgoing Mail Server (SMTP) settings.

1. Correct Your SMTP Settings

Check your email program (Outlook, Apple Mail, Thunderbird, etc.) and ensure the following:

  • Outgoing Mail Server (SMTP): smtp.roadrunner.com
  • Port: 465 (SSL/TLS) or 587 (STARTTLS)
  • Authentication Required: YES (critical)
  • Enter your full Roadrunner email address and password in the authentication fields.

2. Disable Conflicting Security Software

  • Antivirus or firewall programs can block SMTP connections.
  • Temporarily disable your antivirus/firewall.
  • Try sending an email.
  • If it works, re-enable your software and configure it to allow Roadrunner email.

Fixing “Unable to Receive Email” (IMAP/POP3 Errors)

If you can send emails but cannot receive them, the problem is likely with your Incoming Mail Server settings.

1. Verify Your Incoming Server Configuration

Use either IMAP or POP3. IMAP is strongly recommended.

IMAP Settings (recommended):

Incoming Server: imap.roadrunner.com

  • Port: 993
  • Encryption: SSL/TLS
  • POP3 Settings:

Incoming Server: pop.roadrunner.com

  • Port: 995
  • Encryption: SSL/TLS

2. Check for a Full Mailbox

  • Roadrunner accounts have limited storage. If your mailbox is full, new messages cannot be received.
  • Log in to webmail and delete old emails, especially with large attachments.
  • Empty your Trash and Spam folders.

Advanced Solutions for Stubborn Problems

1. Remove and Re-add Your Account

This fixes corrupted account profiles, especially on mobile devices or desktop clients:

  • Write down your server settings.
  • Remove your Roadrunner account from your device.
  • Restart the device.
  • Add the account again manually with the correct settings.

2. Update or Reset Your Password

Authentication failures can block both sending and receiving:

  • Reset your Roadrunner password at https://webmail.roadrunner.com
  • Update the password on all devices and email clients.

3. Clear Your Email Client Cache

  • Corrupted local caches in programs like Outlook can cause sync issues. Use built-in repair tools to clear the cache or repair the mailbox data file.
  • If issues persist, call Roadrunner Customer Support at 1-877-337-8298 for account-specific assistance.

Frequently Asked Questions (FAQ)

Q1: Why do I keep getting “SMTP Authentication Error” in Roadrunner?

This occurs when your email client cannot verify your identity with the outgoing server. Ensure authentication is ON and use your full email and password.

Q2: What port should I use for the Roadrunner SMTP server?

465 (SSL/TLS) or 587 (STARTTLS). Port 465 is most commonly successful.

Q3: My emails aren’t syncing on my iPhone. What should I do?

This is usually an IMAP issue. Delete the account (Settings > Mail > Accounts) and re-add it using:

Incoming: imap.roadrunner.com (Port 993, SSL/TLS)

Outgoing: smtp.roadrunner.com (Port 465, SSL/TLS)

Q4: I can log into webmail but not my email client. Why?

Your account is active, but the client settings are incorrect. Remove and re-add the account with correct server info.

Log in to webmail, delete old emails, and empty Trash and Spam folders.

Q7: My antivirus keeps blocking emails. What do I do?
