Redmine

i'm install redmine 3.2.2 + git 1.7.1

and then

setting :
1. setting git hooks/update ( git server side)
: check redmine issue keyword(fix|ref) and issue number in commit message, if no match..exit 1 (fail)
: check all commit message

but...problem

workflow
1. creat redmine git repository (host name : devserver)
2. setting git update hook (hooks/update)
3. client : git clone devserver
4. client : git work.... something
5. client : git remote add github-test https://github.com/xxx/xxx (github commit message has no issue keyword )
6. client : git pull github-test master ( many commit message )
7. client : git push origin master
: reject , not found issue keyword (commit message of github-test)

... question ?
if pull, fetch or merge for remote repository, Can i skip the issue keyword checks?(server side)
