| FAIL | MX is host name, not IP | ERROR: You have one or more MX record(s) that contain an IP address. This is not valid. A fully RFC-compliant mailserver will not be able to send you mail (although some mail servers will, due to the TCP/IP functions that they use). The problem MX records are: 11.22.33.44. |
| FAIL | Reverse DNS entries for MX records | ERROR: None of your mail server(s) seem to have reverse DNS (PTR) entries (I didn't get any responses for them). RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. You can double-check using the 'Reverse DNS Lookup' tool at the DNSstuff site (it contacts your servers in real time; the reverse DNS lookups in the DNS report use our local caching DNS server). |
| FAIL | Connect to mail servers | ERROR: I could not complete a connection to any of your mailservers! 11.22.33.44: Could not connect without glue or A record. If this is a timeout problem, note that the DNS report only waits about 40 seconds for responses, so your mail *may* work fine in this case but you will need to use testing tools specifically designed for such situations to be certain. |
越弄越复杂了,我的邮件服务器已经正常运行了几个月,包括去网站上查询的DNS解析都没有,就今天出现问题了,只是想确认下是否是服务供应商那里出了问题,我的服务器没有变动过| 欢迎光临 邮件服务器-邮件系统-邮件技术论坛(BBS) (http://bbs.5dmail.cn/) | Powered by Discuz! X3.2 |
