[Mail] 如何用maildrop来知道一封信中有附件？

[weixin_38066537]

我使用下面的方法来检查邮件中是否带有附件。主要是依靠识别关键字
Content-Disposition: attachment;

但是日志中总是显示 no attachment
请教我的规则中，哪里写错了？

import EXT
import HOST
VHOME=`/home/vpopmail/bin/vuserinfo -d $EXT@$HOST`
logfile "/var/log/mail/maildrop/$HOST"

if (/^Content-Disposition: attachment;/)
{
log "with attachment"
log $MATCH
to "/home/vpopmail/domains/spam/Maildir/."
exit
}

log "no attachment"
to "$VHOME/Maildir/."
