论坛邮件设置建议

论坛邮件居然进了我的垃圾箱,我看了看——

X-Spam-Status: Yes, score=4.5 required=3.0 tests=FROM_EXCESS_BASE64,
        HTML_MESSAGE,MIME_HTML_ONLY,PHP_ORIG_SCRIPT,RDNS_NONE,
        TVD_SPACE_RATIO_MINFP autolearn=no autolearn_force=no version=3.4.2
X-Spam-Report:
        *1.1 MIME_HTML_ONLY BODY: Message only has text/html MIME parts
        *0.0 HTML_MESSAGE BODY: HTML included in message
        *1.3 RDNS_NONE Delivered to internal network by a host with no rDNS
        *0.1 FROM_EXCESS_BASE64 From: base64 encoded unnecessarily
        *2.0 PHP_ORIG_SCRIPT Sent by bot & other signs
        *0.0 TVD_SPACE_RATIO_MINFP Space ratio


建议:
1. 邮件格式使用multipart
2. 邮件服务器弄个Reverse DNS,并且相关域名也解析到这个IP
3. (如果可以的话)想办法让机发特征消失
