Troubleshooting

Why can't I send messages through my personal mail server when I'm connected to Frontier High-Speed Internet?

Frontier blocks all SMTP (Port 25) traffic over our network that is not sent through Frontier outgoing mail servers (smtp.frontier.com). We’re sorry for any inconvenience this may cause.

This only applies if you have a dynamic IP address. If you have Frontier Business Class High-Speed Internet (or SDSL) and a static IP address, your outgoing email will not be affected.

If this has affected you, please change your outgoing mail server to smtp.frontier.com.

You might also have to configure your email program to authenticate to our outgoing mail server. To find out how to do this, visit our SMTP Authentication FAQs.

Note: Some customers telecommuting from home may be unable to send email using their companies' email systems. For your own security, we suggest establishing a secure connection via an application, such as VPN, in order to utilize the outgoing mail server for your place of business.
