Optus outgoing mail server settings

Here are the Optus outgoing mail server settings:

SMTP Server:

• Server: smtp.optusnet.com.au
• Port: 25 or 587 (TLS/STARTTLS)

Authentication:

• Username: Your Optus email address (e.g., [email protected])
• Password: Your Optus email password

Notes:

• If you're using a third-party email client or app, you may need to enable TLS/STARTTLS encryption to connect to the SMTP server.
• If you're having trouble sending emails, try using port 587 instead of 25, as some ISPs block port 25 for security reasons.
• If you're using a mobile device or public Wi-Fi, you may need to use a VPN to connect to the Optus network before sending emails.

Additional Tips:

• Make sure your email client or app is configured to use the correct outgoing mail server settings.
• If you're having trouble sending emails, check your email client or app's settings to ensure that the outgoing mail server is set to smtp.optusnet.com.au.
• If you're still having trouble, try contacting Optus support for further assistance.
