![使用 exim 从 vm1 向 vm2 发送电子邮件时无法路由地址](https://linux22.com/image/732707/%E4%BD%BF%E7%94%A8%20exim%20%E4%BB%8E%20vm1%20%E5%90%91%20vm2%20%E5%8F%91%E9%80%81%E7%94%B5%E5%AD%90%E9%82%AE%E4%BB%B6%E6%97%B6%E6%97%A0%E6%B3%95%E8%B7%AF%E7%94%B1%E5%9C%B0%E5%9D%80.png)
我正在尝试从虚拟机 1 向虚拟机 2 发送电子邮件,但出现了错误Unroutable address
,具体来说dnslookup_relay_to_domains router declined for user@lab1
查看 exim 文档我发现了这一点This option specifies a text message that is used when an address cannot be routed because Exim has run out of routers. The default message is “Unrouteable address”
,但我仍然不明白如何解决这个问题。
虚拟机 1 的主机名是lab1
,IP 地址是10.0.2.5
虚拟机 2 的主机名是lab2
,IP 地址是10.0.2.6
以下是 update-exim4.cong.conf 中的设置:
dc_eximconfig_configtype='internet'
dc_other_hostnames='lab2; localhost'
dc_local_interfaces='127.0.0.1'
dc_readhost=''
dc_relay_domains='lab1'
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost=''
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='false'
dc_mailname_in_oh='true'
dc_localdelivery='maildir_home'
模拟exim -bhc
发送电子邮件到 10.0.2.5 我得到:
>>> routing user@lab1
>>> expansion of "${if exists{/etc/exim4/hubbed_hosts}{partial-lsearch;/etc/exim4/hubbed_hosts}fail}" forced failure: assume not in this list
>>> lab1 in "! +local_domains : +relay_to_domains"? yes (matched "+relay_to_domains" - cached)
>>> R: dnslookup_relay_to_domains for user@lab1
>>> calling dnslookup_relay_to_domains router
>>> dnslookup_relay_to_domains router declined for user@lab1
>>> "more" is false: skipping remaining routers
>>> no more routers
>>> ----------- end verify ------------
>>> require: condition test failed in ACL "acl_check_rcpt"
>>> end of ACL "acl_check_rcpt": not OK
550 Unrouteable address
LOG: H=(mail) [10.0.2.6] F=<user@lab2> rejected RCPT user@lab1: Unrouteable address
答案1
我尝试了很多方法,但配置有点混乱。最后我终于解决了这个问题,并使用了“由智能主机发送的邮件”的配置。我对配置进行了以下更改:
dc_eximconfig_configtype='internet'
变成dc_eximconfig_configtype='smarthost'
dc_relay_domains='lab1'
变成dc_relay_domains=''
dc_smarthost=''
变成dc_smarthost='lab1'
