I'va added sender in global whitelist, but anyway message from this sender go to quarantined mails as "Bad Header". This emails from software which sending info emails to subscribers and I can't modify any system info like HEADER in this software 
Plugin amavisd_wblist enabled in config file.
How can I bypass amavis header check for whitelist?
Thank you
