大家建立的exchange都是在固定的IP下建立起来的么???我这边是ADSL动态IP的,现在建立起来的exchange邮件服务器,在发送邮件中,发现有一部份邮件发送不出去,对方服务器拒收:
<mailserver.szhyhh.com #5.5.0 smtp;550 DY-001 Unfortunately,
messages from 121.15.119.90 weren't sent. Please contact your Internet
service provider. You can tell them that Hotmail does not relay
dynamically-assigned IP ranges. You can also refer your provider to
htt://mail.live.com/mail/troubleshooting.aspx#errors.>
目前我知道的,可以使用邮件中继服务解决这个问题,不知道还有没有别的好方法,能不能不用付费的呢??
请问大家有什么好的解决方案么???
