能不能用javamail来删除邮件服务器上的邮件

是用下面的代码： try { mState = NONE; Properties props = System.getProperties(); props = System.getProperties(); if (mailType == MailType.TYPE_GMAIL) { // 如果为gmail邮箱，需要设置下两项 props.put("mail.smtp.starttls.enable", "true"); props.put("mail.smtp.port", "587"); // gmail smtp port 587 / 465 } props.put("mail.smtp.host", mSmtp_host); props.put("mail.smtp.user", mFrom_userName); props.put("mail.smtp.password", mFrom_passWord); props.put("mail.smtp.auth", "true"); mSession = Session.getDefaultInstance(props, null); mSession.setDebug(false); mMimeMsg = new MimeMessage(mSession); mMimeMsg.setFrom(new InternetAddress(mFrom_userName)); // mMimeMsg.setContent(mContent, "text/html;charset=utf-8"); if (mToId != null) setSendToMsg(mToId); if (mCcId != null) setCopyToMsg(mCcId); if (mBccId != null) setBCopyToMsg(mBccId); if (mSubject != null) { mMimeMsg.setSubject(mSubject); } if (mShow_name != null) { mMimeMsg.setFrom(new InternetAddress(mShow_nam... 我是用下面的代码：
