Go to Setup > Other > Settings > Mail Settings to configure the system-wide email settings.
Note: If you do not set up your domain email address, CLM uses the default From Address, which is firstname.lastname@example.org to deliver emails.
This is the default email address that will be used when an email is sent out from CLM. This is the "send as" email address and is mandatory.
If you do not set up your custom domain email address, CLM uses the default From Address, which is email@example.com to deliver emails. You can use the default settings or set up your domain email address, such as firstname.lastname@example.org.
You can also create a no-reply email address, such as email@example.com. A no-reply email address informs the recipient that replies sent to this email address will not be received or monitored.
This is the reply-to address to which responses to out-of-office emails must be sent.
If not specified, the email address of the user who executes the workflow action is used and the auto-reply email is sent to that email address.
This is the address to which notifications of undeliverable emails must be directed (same as smtp.mailfrom).
This setting also impacts the SPF record. If Return-Path is different from From Address, the remote SMTP server checks the SPF record of Return-Path instead of From Address.
If Return-Path is different than From Address, the delivery notifications are sent to Return-Path instead of From Address.
If Return-Path is not specified, the email address of the user who executes the workflow action is used and notifications are delivered to that email address.
Note: It is recommended that you engage your IT department to configure the Mail Settings and the Sender Policy Framework (SPF) record. It is important to configure these settings properly to pass the SPF check and prevent your emails from being marked as spam.
