@vcancy 十分感谢你的PR, 下面是我的一点建议：

1. 以后所有的feature的配置全部建议放在feature_[feature name]的section里面， 这样逻辑更清晰

[feature_serverchan]
enabled=false
sckey = 

2. 如果新功能的配置全部放在feature_xxx的section中的话， 需要修改config.py过滤掉feature_开头的section

FROM:

    def get_domain_record_sections(self):
        """
        Get sections other than default, which contains DomainRecord definition
        :return: section list
        """
        return self.parser.sections()

TO:

    def get_domain_record_sections(self):
        """
        Get sections other than default, which contains DomainRecord definition
        :return: section list
        """
        # filter out feature_sections
        sections = self.parser.sections()
        return [ s for s in sections if not s.lower().startswith("feature_") ]

3. 在读取serverchan配置的时候，因为之前版本的serverchan相关的配置选项不是必须的，为了与以前的配置文件兼容，不会导致用户由于更新了新版本因为读取不到serverchan的配置而出错，建议在config.py这样处理：

if not self.access_id or not self.access_key:
            DDNSUtils.err_and_exit("Invalid access_id or access_key in config file.")

# if we specify section "feature_serverchan", then we need read the required options
if self.parser.has_section("feature_serverchan"):
    self.get_feature_serverchan_options()

def get_feature_serverchan_options():
    section_name = "feature_serverchan"
    try:
        enabled = self.parser.getboolean(section_name, "enabled")
    except ValueError as ex:
        DDNSUtils.err_and_exit("Invalid 'enabled' value in feature serverchan config: {0}".format(ex))
    except ConfigParser.NoOptionError as ex:
        enabled = False

    if enabled:
       try:
           sckey = self.parser.getboolean(section_name, "sckey")
       except ConfigParser.NoOptionError as ex:
           DDNSUtils.err_and_exit("No sckey specified")

    if sckey == "":
        DDNSUtils.err_and_exit("Empty serverchan sckey")

    self.serverchan_enabled = enabled
    self.serverchan_sckey = sckey

3. 为效率考虑，在ddns.py里面判断self.serverchan_enabled is True的时候才去调用push_serverchan_msg()

if not remote_record:
              DDNSUtils.err("Failed finding remote DomainRecord" \		              DDNSUtils.err("Failed finding remote DomainRecord" \
                            "[{rec.subdomain}.{rec.domainname}]".format(rec=local_record))		                            "[{rec.subdomain}.{rec.domainname}]".format(rec=local_record))
             if config.serverchan_enabled:
                    DDNSUtils.push_serverchan_msg(config.serverchan_sckey,"更新DNS失败:外网IP[{remote}]".format(remote=remote_record.value))
...

4. 在push_serverchan_msg()里面需要用try...except处理错误，以防影响主功能的运行。

    try:
         requests.get('https://sc.ftqq.com/{}.send?text={}&desp={}'.format(sckey,title,msg)
    except:
         pass

5. 建议能不能在Readme里面加入"server酱"功能的基本介绍以及各个参数代表的意思，以及简单示例配置
