When the "Enable Background Email" option is activated in the Employee Portal Setup (General Tab), failed emails are logged and stored in a designated location. After resolving the issue, you can resend the email by selecting it with the checkbox and clicking the "Resend" button.
Common undeliverable reasons:
Incorrect configuration of the email server (refer to "How to define Email Server (SMTP Server) in HRPro?")
SMTP port blocked by the firewall
Invalid password or requirement for an alternate password for external applications
External application access disabled
Mailbox capacity exceeded
Maximum number of concurrent connections surpassed
The limit on messages per minute was exceeded
The limit on messages per day was exceeded
The "Delete" button becomes available when the "Enable Delete Undeliverable Email" checkbox is activated in the Employee Portal Setup (General Tab). This allows users to delete the log instead of resending the email.
