Free mail server yahoo

I think there may be some confusion here!

Yahoo is a web-based email service, not a free mail server. A mail server is a software application that handles email messages, whereas Yahoo is a web-based email service that allows users to access their email accounts through a web interface.

That being said, if you're looking for a free mail server solution, there are several options available. Here are a few:

1. OpenSMTPD: An open-source mail server that can be installed on a Linux or BSD system.
2. Postfix: Another popular open-source mail server that can be installed on a Linux or BSD system.
3. Sendmail: A free and open-source mail server that can be installed on a Linux or BSD system.
4. Mail-in-a-Box: A free, open-source mail server solution that includes a web interface and can be installed on a Linux system.
5. Mailhog: A free, open-source mail server that can be installed on a Linux or Windows system.

Please note that setting up a mail server requires some technical expertise and can be complex. Additionally, you'll need to ensure that your mail server is properly configured and secured to prevent spam and other security issues.

If you're looking for a simple, web-based email solution, you may want to consider using a free email service like Gmail, Outlook, or ProtonMail, which offer a range of features and are easy to use.
