构建发送邮件参数

	//imSentMessage 是封装了邮件信息的实体对象
    public ExchangeClient convertExchange(ImSentMessage imSentMessage) {
        if (filterNull(imSentMessage)) return null;
        EmailServerProperty server = switchEmailServer(imSentMessage.getCorpCode());
        if (null == server) return null;
        ExchangeClient.ExchangeClientImplBuilder builder = new ExchangeClient.ExchangeClientImplBuilder();
        builder.username(server.getSmtpAccount());
        builder.password(server.getSmtpPassword());
        builder.exchangeVersion(ExchangeVersion.Exchange2010_SP2);
        builder.message(imSentMessage.getMessageContent());
        builder.subject(imSentMessage.getMessageTitle());
        builder.hostname(server.getSmtpHost());
        builder.userid(imSentMessage.getImUser().getUserId());
        builder.corpCode(imSentMessage.getImUser().getCorpCode());
        //收件人
        builder.recipientTo(imSentMessage.getImUser().getEmail());
        convertExchangeAttachment(builder, imSentMessage.getAttachmentFile());
        return builder.build();
    }
//构建成功之后直接调用sendExchange即可发送邮件,发送的时候建议使用多线程提高发送效率
