It's likely some post/pre custom configs, or not latest versions of exim/eximconf.
/usr/local/directadmin/custombuild# ls -alh ...
-rw-r--r-- 1 root root 2.5M Jun 21 12:56 exim-4.94.tar.gz
exim=yes
eximconf=yes
eximconf_release=4.5
clamav=no
mailman=no
spamassassin=yes
mail-header-patch=no
dovecot=yes
I don't have any custom configurations.
The exim.conf diff from the da server (
http://files.directadmin.com/services/exim.conf) compared to the /etc/ one:
/tmp/direct# diff exim.conf /etc/exim.conf
607c607,608
< user = "mail"
---
> user = "${lookup{$domain}lsearch{/etc/virtual/domainowners}{$value}}"
> group = "mail"

< file_transport = address_file
---
> directory_transport = address_file
769c770,773
< file = /var/mail/$local_part
---
> directory = /home/$local_part/Maildir/
> directory_mode = 770
> create_directory = true
> maildir_format
781c785
< directory_mode = 700
---
> directory_mode = 770
783c787,788
< file = /var/spool/virtual/${domain}/${local_part}
---
> directory = /home/${lookup{$domain}lsearch*{/etc/virtual/domainowners}{$value}}/imap/${domain}/${local_part}/Maildir
> maildir_format
Which, as far as I understand is patched by ./build exim_conf
Am I missing something?
