Hi,
We encountered this issue, too - many of our systems are setup in the
smarthost config, with /etc/mailname set to sanger.ac.uk. This mostly
works - central LDAP means that user fred will reliably by fred at
sanger.ac.uk, and so on.
The downside is that we can't then e.g. alias 'root' so that cron-mail
goes to the person/team best placed to deal with it, and root at
sanger.ac.uk gets too much automated email.
This is because:
i) qualify_domain is not a member of local_domains; so the qualified
address root@qualify_domain is not considered by the system_aliases router
ii) in any case the smarthost router occurs before the system_aliases
router, so even if you fix the above, it doesn't help
What we did was to change
domains = +local_domains
in the system_aliases router to
domains = +local_domains : $qualify_domain
To address point i) and then move the
router/400_exim4-config_system_aliases block earlier in the config file
(between router/150_exim4-config_hubbed_hosts and
router/200_exim4-config_primary) - a similar effect can be achieved
using the split files, obviously
I think this is a common enough configuration that providing better
support for it in Debian would be useful - you could have a conditional
block do the aliasing router earlier for smarthosts, or a separate
alias-style router that just did qualify_domain, according to maintainer
taste. But I think it's something that Debian could support more
straightforwardly for users without much extra maintenance effort, so
maybe Debian should do so?
Regards,
Matthew
