We have a particular issue with Mailman (more of an exim issue actually) cannot delivers email to our canby.k12.... domain. Emails send to this domain come back with this error (-53): retry time not reached for any host. Other emails went out OK.
When we run the exim -d -M message_ID, here is a portion of the log file: >>>>>>>>>>>>>>>> Remote deliveries >>>>>>>>>>>>>>>> --------> csdad...@canby.k12.or.us <-------- search_tidyup called changed uid/gid: remote delivery to csdad...@canby.k12.or.us with transport=remote_smtp uid=93 gid=93 pid=15280 auxiliary group list: <none> set_process_info: 15280 delivering 1VitQf-0003yJ-96 using remote_smtp remote_smtp transport entered csdad...@canby.k12.or.us checking status of canby.k12.or.us locking /var/spool/exim/db/retry.lockfile locked /var/spool/exim/db/retry.lockfile EXIM_DBOPEN(/var/spool/exim/db/retry) returned from EXIM_DBOPEN opened hints database /var/spool/exim/db/retry: flags=O_RDONLY dbfn_read: key=T:canby.k12.or.us:10.30.XXX.XX dbfn_read: key=T:canby.k12.or.us:10.30.XXX.XX:1VitQf-0003yJ-96 no message retry record canby.k12.or.us [10.30.192.16] status = usable 10.30.XXX.XX in serialize_hosts? no (option unset) delivering 1VitQf-0003yJ-96 to canby.k12.or.us [10.30.XXX.XX] (csdad...@canby.k12.or.us) set_process_info: 15280 delivering 1VitQf-0003yJ-96 to canby.k12.or.us [10.30.XXX.XX] (csdad...@canby.k12.or.us) set_process_info: 15279 delivering 1VitQf-0003yJ-96: waiting for a remote delivery subprocess to finish The 10.30.xxx.xx is a masked IP to protect our DNS service. Our domain is canby.k12... while our email is canby.k12... and hosted by an external provider. According to the log file, it seems that Mailman thinks canby.k12... domain is hosted at 10.30.xxx.xx, which is our internal DNS service. Is there a tool for us to trace the email sending route? We suspect it is the DNS setting but need more info to determine where does it stop. Do we need an MX record, A record or something else in our DNS service so Mailman not try to connect to this DNS server and end up failing? We can post the exim config file if needed.
