(有点长.....)<br>
公司原来使用的是万网的虚拟主机和企业邮箱,邮件收发一直很正常;后更换了万网独立主机,购买并自己架设了金笛邮件系统,却出现了许多退信,国内的sina,sohu,163,126均是退信,给国外的一些客户发邮件也被退,收邮件全部正常 以下是部分退信信息:<br>
<br>
550 5.7.1 Unable to relay for kgreen@laserex.net<br>
<br>

<br>
550 relaying to <MSeymour@visioneng.com> prohibited by administrator (failed to find host name from IP address)<br>

<sales@cdhcorp.com.cn>: host mail.cdhcorp.com.cn[211.157.108.132] said:504 TurboMail only server for local user<br>
<br>
经询问金笛的技术支持,说是IP可能被屏蔽拒收造成的,建议我做了DNS反向解析,但问题依旧。后建议我更换IP,但据我所知更换IP也不一定能解决问题,我去"中国反垃圾邮件联盟 <a target=_blank href=http://anti-spam.org.cn">http://anti-spam.org.cn"</a>; 用 "黑名单列入验证查询 "在 CBL CDL ORDB DSBL NJABL MAPS SPAMHAUS等各大黑名单中并未发现我公司的IP 。<br>

<br>
我现在就不太清楚到底什么原因引起退信?<br>
我更换了 IP 要还是有退信 该怎么办?<br>
怎样才能解决退信的问题?<br>
期待您的帮助,谢谢。<br>
