E-Mail Security Virtual Appliance (ESVA)

Solving release quarantine email issues

Sometime when you click the release link in an email quarantined report, you still get a new spam report instead of the email released. This seems like the mail kept running re-release and re-quarantined loop. The easiest way to solve this issue is to bypass the "[email protected]" in our ESVA

Step 1. Login into ESVA console

Step 2. Edit file /etc/MailScanner/MailScanner.conf

vi /etc/MailScanner/MailScanner.conf

Step 3. Modify according to following lines

Go to Spam Checks line, then change it to the following line. This will tell the ESVA to running the Spam Checkings rulkes accoding to spamscan.rules that we will cusotmise later.

Spam Checks = %rules-dir%/spamscan.rules

Step 4. Create a new scanning rule

Next, let us create a new rules called spamscan.rules under /etc/MailScanner/rules

vi /etc/MailScanner/rules/spamscan.rules

Then, add in the following lines. As you can see we are bypass all email from [email protected], while we are leaving all other emails as deafult.

From: [email protected] no FromOrTo: default yes

Step 5. Save it

:wq

Step 6. Reboot the Mailscanner servers

service MailScanner restart
