错误：

<liuyb@5teacher.com>: Command died with status 127: "maildrop". Command output:

sh: liuyb@5teacher.com: command not found

解决办法：

vim /var/www/extsuite/extmail/libs/Ext/MailFilter.pm

在412行

#*mail2sms
"cc \"|"\$MAIL2SMS \\\"\$FROM\\\"\"\n";

删除或者修改成

"cc \"\$MAIL2SMS \\\"\$FROM\\\"\"\n";

找到所有.mailfilter文件

cd /home/domains/xxxx.com/

find .  -maxdepth 2 -name .mailfilter

删除所有.mailfilter文件即可。一般就可以了。

使用 rm命令删除所有.mailfilter即可。
