Postfix/cleanup warning

[Rytec]

Dear members, I have changed today some things in the behaviour of the header checkup, I'm using the file from Jim Sun http://jimsun.linxnet.com/misc/header_checks.txt but in the mail logging it gives me this error : postfix/cleanup[2878]: warning: regexp map /etc/postfix/header_checks, line 92: Invalid preceding regular _expression_ I already have commented out all the check lines by putting the "#" in front of each line but it still gives me this error. I'm using Ubuntu server LTS 10.04 with Postfix, maybe his header-check file is not made to use with Ubuntu Linux? thanks for your help Ryan
