The Mail Sending Settings give you the ability to route returned email or replies to email to a specific address. If your store is running on an SMTP or Windows server, you can verify the host and port settings.

IMPORTANT
Security Notice All merchants should immediately set their mail sending configuration to protect against a recently identified potential remote code execution exploit. Until this issue is resolved, it is highly recommended that you avoid using Sendmail for email communications. In the Mail Sending Settings, make sure that Set Return Path is set to No.

For a detailed list of the configuration settings, see Mail Sending Settings in the Configuration Reference.
