postfix+amavis 附件大于2M发不出去问题，急！
main.cf文件：
message_size_limit = 52428800
mailbox_size_limit = 209715200
body_checks_size_limit = 52428800
content_filter = smtp-amavis:[localhost]:10024
附件大于2M就发不出去
maillog如下：

如果附件小于2M就没问题。
如果在main.cf中去掉content_filter = smtp-amavis:[localhost]:10024
附件大于2M也能成功发出去。
哪里有问题，请大家帮帮忙！
