AIUI exim should be able to deliver emails into a user's mbox, but I'm confused about how exim is meant to do that, because it runs as user Debian-exim, but mailbox permissions are normally group:mail.
For example, with exim4 on hostR set up as … internet site; mail is sent and received directly using SMTP Domains to relay mail for: hostS;corp Keep number of DNS-queries minimal (Dial-on-Demand)? Yes dc_eximconfig_configtype='internet' dc_relay_domains='hostS;corp' dc_minimaldns='true' … hostS can send an email to foo@hostR without its being rejected. At the receiving end, with these lines in /etc/exim4/hubbed_hosts, … hostR.corp: 192.168.1.18 mail_spool hostR: 192.168.1.18 mail_spool … when exim tries to deliver this email directly, the exim log shows … 1hyefl-0001RE-Up <= [email protected] H=(hostS.corp) [192.168.1.17] P=esmtp S=711 [email protected] 1hyefl-0001RE-Up == [email protected] R=hubbed_hosts T=mail_spool defer (-6): mailbox /var/mail/foo has wrong uid (1003 != 111) … and the email remains stuck in /var/spool/exim. Background info: etc/passwd on hostR: mail:x:8:8:mail:/var/mail:/usr/sbin/nologin Debian-exim:x:111:120::/var/spool/exim4:/usr/sbin/nologin foo:x:1003:1003:Mr Chew,,,:/home/foo:/bin/bash ps -ef on hostR: 9659 1 111 ? Ss 0:00 /usr/sbin/exim4 -bd -q30m ls on hostR: drwxrwsr-x 2 root mail 4096 Aug 16 13:24 /var/mail/ -rw-rw---- 1 foo mail 19284 Aug 16 12:00 /var/mail/foo -rw-rw---- 1 Debian-exim mail 670 Aug 16 13:24 /var/mail/root So what piece of the puzzle is missing that would allow exim to deliver such an email to foo's mbox? Exim has no difficulty, for example, delivering locally generated emails from cron … 1hyfaG-00027u-Mt <= [email protected] U=root P=local S=91975 1hyfaG-00027u-Mt => foo <foo@localhost> R=local_user T=mail_spool 1hyfaG-00027u-Mt Completed … nor in delivering remotely sent emails to root: 1hygu1-0002c1-A7 <= [email protected] H=(hostS.corp) [192.168.1.17] P=esmtp S=734 [email protected] 1hygu1-0002c1-A7 => [email protected] R=hubbed_hosts T=mail_spool H=192.168.1.18 1hygu1-0002c1-A7 Completed Cheers, David.
