Answer
If you are questioning why an email was blocked or allowed by the Anti-Spoofing module and would like more information, you can find further details in the log file for that filter. Use the following procedure to find the log and information regarding your message within it, and then use the examples below to interpret why the message was either blocked or allowed:- Find the message ID of the email in question by either gathering it from the headers of the message itself, or by looking for it in the MailEssentials Dashboard > Logs > Details tab
-
Open the ase_antispoofing.gfi_log file in notepad from ..\GFI\MailEssentials\AntiSpam\DebugLogs
- This log is for the Anti Spoofing Module and corresponds to the Configuration > Anti-Spam > Anti Spam Filters > Anti Spoofing in the interface and the antispoofing_ip_list table within the config.mdb

Do a search for the Message ID from the dashboard or the email headers
