简单的zimbra fillter设置脚本上的意外标记附近的语法错误

Question

好的，所以我在centos 6上运行zimbra 7，并且使用不同的源代码，我编写了以下脚本：

MAIL="$(< scripts\mails.txt)" #mails from mails.txt file
for MAIL in $MAILS; do
zmmailbox -z -m $MAILS cf -c red "/SPAM"
zmmailbox -z -m $MAILS afrl "Spam" active any header "subject" contains "your account" header "subject" contains "facebook" header "subject" contains "google" header "subject" contains "paypal" header "subject" contains "virus" header "subject" contains "invoice" fileinto "SPAM" stop   
done

但每当我运行它（作为zimbra用户）时，我都会收到以下错误：

./fillter-set.sh: line 5: syntax error near unexpected token `zmmailbox'
./fillter-set.sh: line 5: `zmmailbox -z -m $MAILS cf -c red "/SPAM"'

任何人都可以告诉我我做错了什么以及如何修复脚本以便我可以运行它？
