今天收到同事反馈，说发邮件给邮箱组，收到退信提示: Command died with status 127: "maildrop". Command output: sh: xxx@xx.com: command not found。日志也没有相关错误提示，以下是解决办法

修改.mailfilter
find /home/domains/xx.com -maxdepth 2 -name '.mailfilter' -exec sed -i '/SENDMAIL/s/"/"|/' {} \;
sed -i '/MAIL2SMS/s/"|/"/' /var/www/extsuite/extmail/libs/Ext/MailFilter.pm

也可以把.mailfilter删掉，或者把.mailfilter中的"cc \"|"\$MAIL2SMS \\\"\$FROM\\\"\"\n";删掉
