Backup and restore mail filters on a new ZCS

[desport]

Hello,

I noticed that the REST method doesn't save the filters rules :
zmmailbox -z -m aide@mydomain.com getRestURL //?fmt=tgz > /mail/export/backup/accounts/aide.tgz

So I tried these commands :
- backup

zmmailbox -z -m aide@mydomain.com >> filters

- restore script on the new zcs

exec < filters
while read line
do
zmmailbox -z -m aide@mydomain.com addFilterRule $line
done

Restore fails because of spaces in rules name, folders...
