    Hi  

    Thank you for reaching out to the community!

    To investigate your issue further, we need to check smtpd_main logs in debugging.

    Follow this KB Article to get SSH access: Sophos XG Firewall: How to SSH to the firewall using PuTTY utility

    • Type 5 and then 3 to access the Advanced shell.
    • Run this command to put smtpd service in debug: service smtpd:debug -d -s nosync
    • Replicate the issue and collect smtpd_main.logs by running: tail -f smtpd_main.log

    Note: Run the same command to remove debug. 

    Provide these logs via PM or post it on this thread.

    Thanks,
