Re: Allow this type of password protected file

To do this just for that sender:

MailScanner.conf: (Typically in /etc/MailScanner)

Allow Password-Protected Archives = %rules-dir%/password.rules

In password.rules in your %rules-dir% (Typically in 
/etc/MailScanner/rules), tab separated:

From: [email protected]    yes

FromOrTo:    default     no
