1and1 mail smtp require ssl for email

1&1 Ionos (formerly 1and1) requires SSL (Secure Sockets Layer) or TLS (Transport Layer Security) encryption for sending emails using their SMTP server.

Here are the details:

• SMTP Server: mail.1and1.com
• Port: 587 (Submission) or 25 (SMTP)
• Encryption: SSL/TLS (required)
• Username: Your 1&1 Ionos email address (e.g., [your_email_address]@1and1.com)
• Password: Your 1&1 Ionos email password

To set up your email client to use 1&1 Ionos' SMTP server with SSL/TLS encryption, follow these general steps:

1. In your email client, go to the settings or preferences and look for the "Outgoing Mail Server" or "SMTP" settings.
2. Enter the SMTP server address: mail.1and1.com
3. Set the port to 587 (Submission) or 25 (SMTP)
4. Select "SSL" or "TLS" as the encryption method
5. Enter your 1&1 Ionos email address and password
6. Save your changes

Some popular email clients and their specific settings are:

• Microsoft Outlook: Go to File > Account Settings > Account > More Settings > Outgoing Server > Use the following outgoing server (SMTP) > mail.1and1.com > Port 587 > Use SSL/TLS
• Mozilla Thunderbird: Go to Tools > Account Settings > Outgoing Server (SMTP) > mail.1and1.com > Port 587 > Use SSL/TLS
• Apple Mail: Go to Mail > Preferences > Accounts > Outgoing Mail Server > mail.1and1.com > Port 587 > Use SSL/TLS

Remember to replace "mail.1and1.com" with your actual 1&1 Ionos email address.
