I recently upgraded from wheezy to jessie. I did a fresh install. During the
install, I configured exim4 the same way that I did under wheezy. I have been
configuring it the same way since sarge, etch, lenny, and squeeze. I keep
records of the answers that I give to dpkg-reconfigure exim4-config. Enclosed
are the answers that I gave during the jessie install.

# Edit this file and /etc/mailname by hand and execute update-exim4.conf
# yourself or use 'dpkg-reconfigure exim4-config'
#
# Please note that this is _not_ a dpkg-conffile and that automatic changes
# to this file might happen. The code handling this will honor your local
# changes, so this is usually fine, but will break local schemes that mess
# around with multiple versions of the file.
#
# update-exim4.conf uses this file to determine variable values to generate
# exim configuration macros for the configuration file.
#
# Most settings found in here do have corresponding questions in the
# Debconf configuration, but not all of them.

# This is a Debian specific file

root at upplysingaoflun:~#
I ran
# newaliases
I then ran the following test, just on upplysingaoflun:
root at upplysingaoflun:~# mail root
Subject: test1
test1
Cc: root at upplysingaoflun:~# mail root at upplysingaoflun
Subject: test2
test2
Cc: root at upplysingaoflun:~# mail root at upplysingaoflun.ecn.purdue.edu
Subject: test3
test3
Cc: root at upplysingaoflun:~#
test2 got forwarded to qobi at purdue.edu. test1 and test3 did not.
I have changed /etc/mailname to purdue.edu and upplysingaoflun.ecn.purdue.edu.
It makes no difference.
I tried copying /etc/exim4/conf.d/ from a wheezy machine that does forward
root to qobi at purdue.edu. It didn't make a difference.
Under wheezy and all previous versions of Debian for the past decade, mail to
root got forwarded to qobi at purdue.edu. In particular, I just tried test{1,2,3}
above on my one remaining wheezy installation and got the exact opposite
behavior: test1 and test3 got forwarded to qobi at purdue.edu. test2 did not.
I need cron mail, smartctl mail, mdadm mail, etc. forwarded to qobi at purdue.edu.
How do I get this to work under jessie?

Please select the mail server configuration type that best meets your │
│ needs. │
│ │
│ Systems with dynamic IP addresses, including dialup systems, should │
│ generally be configured to send outgoing mail to another machine, called │
│ a 'smarthost' for delivery because many receiving systems on the │
│ Internet block incoming mail from dynamic IP addresses as spam │
│ protection. │
│ │
│ A system with a dynamic IP address can receive its own mail, or local │
│ delivery can be disabled entirely (except mail for root and postmaster). │
│ │
│ General type of mail configuration: │
│ │
│ internet site; mail is sent and received directly using SMTP │
│ mail sent by smarthost; received via SMTP or fetchmail │
│ mail sent by smarthost; no local mail │
│ local delivery only; not on a network │
│ no configuration at this time │
│ │
│ │
│ <Ok> <Cancel>
--------------------------------------------------------------------------------
mail sent by smarthost; received via SMTP or fetchmail
--------------------------------------------------------------------------------
The 'mail name' is the domain name used to 'qualify' mail addresses │
│ without a domain name. │
│ │
│ This name will also be used by other programs. It should be the single, │
│ fully qualified domain name (FQDN). │
│ │
│ Thus, if a mail address on the local host is foo at example.org, the │
│ correct value for this option would be example.org. │
│ │
│ This name won't appear on From: lines of outgoing messages if rewriting │
│ is enabled. │
│ │

Please enter a semicolon-separated list of IP addresses. The Exim SMTP │
│ listener daemon will listen on all IP addresses listed here. │
│ │
│ An empty value will cause Exim to listen for connections on all │
│ available network interfaces. │
│ │
│ If this system only receives mail directly from local services (and not │
│ from other hosts), it is suggested to prohibit external connections to │
│ the local Exim daemon. Such services include e-mail programs (MUAs) │
│ which talk to localhost only as well as fetchmail. External connections │
│ are impossible when 127.0.0.1 is entered here, as this will disable │
│ listening on public network interfaces. │
│ │
│ IP-addresses to listen on for incoming SMTP connections: │

Please enter a semicolon-separated list of recipient domains for which │
│ this machine should consider itself the final destination. These domains │
│ are commonly called 'local domains'. The local hostname │
│ (upplysingaoflun.ecn.purdue.edu) and 'localhost' are always added to the │
│ list given here. │
│ │
│ By default all local domains will be treated identically. If both │
│ a.example and b.example are local domains, acc at a.example and │
│ acc at b.example will be delivered to the same final destination. If │
│ different domain names should be treated differently, it is necessary to │
│ edit the config files afterwards. │

--------------------------------------------------------------------------------
Please enter a semicolon-separated list of IP address ranges for which │
│ this system will unconditionally relay mail, functioning as a smarthost. │
│ │
│ You should use the standard address/prefix format (e.g. 194.222.242.0/24 │
│ or 5f03:1200:836f::/48). │
│ │
│ If this system should not be a smarthost for any other host, leave this │
│ list blank. │

Please enter the IP address or the host name of a mail server that this │
│ system should use as outgoing smarthost. If the smarthost only accepts │
│ your mail on a port different from TCP/25, append two colons and the │
│ port number (for example smarthost.example::587 or │
│ 192.168.254.254::2525). Colons in IPv6 addresses need to be doubled. │
│ │
│ If the smarthost requires authentication, please refer to the │
│ Debian-specific README files in /usr/share/doc/exim4-base for notes │
│ about setting up SMTP authentication. │
│ │
│ IP address or host name of the outgoing smarthost: │
│ │
│ smtp.ecn.purdue.edu______________________________________________________ │
│ │
│ <Ok> <Cancel> │
│
--------------------------------------------------------------------------------
smtp.ecn.purdue.edu
--------------------------------------------------------------------------------
│ The headers of outgoing mail can be rewritten to make it appear to have │
│ been generated on a different system. If this option is chosen, │
│ 'ecn.purdue.edu', 'localhost' and '' in From, Reply-To, Sender and │
│ Return-Path are rewritten. │
│ │
│ Hide local mail name in outgoing mail? │
│ │
│ <Yes> <No>
--------------------------------------------------------------------------------
Yes
--------------------------------------------------------------------------------
The option to hide the local mail name in outgoing mail was enabled. It │
│ is therefore necessary to specify the domain name this system should use │
│ for the domain part of local users' sender addresses. │
│ │
│ Visible domain name for local users: │

--------------------------------------------------------------------------------
In normal mode of operation Exim does DNS lookups at startup, and when │
│ receiving or delivering messages. This is for logging purposes and │
│ allows keeping down the number of hard-coded values in the │
│ configuration. │
│ │
│ If this system does not have a DNS full service resolver available at │
│ all times (for example if its Internet access is a dial-up line using │
│ dial-on-demand), this might have unwanted consequences. For example, │
│ starting up Exim or running the queue (even with no messages waiting) │
│ might trigger a costly dial-up-event. │
│ │
│ This option should be selected if this system is using Dial-on-Demand. │
│ If it has always-on Internet access, this option should be disabled. │
│ │
│ Keep number of DNS-queries minimal (Dial-on-Demand)? │
│ │
│ <Yes> <No>
--------------------------------------------------------------------------------
No
--------------------------------------------------------------------------------
Exim is able to store locally delivered email in different formats. The │
│ most commonly used ones are mbox and Maildir. mbox uses a single file │
│ for the complete mail folder stored in /var/mail/. With Maildir format │
│ every single message is stored in a separate file in ~/Maildir/. │
│ │
│ Please note that most mail tools in Debian expect the local delivery │
│ method to be mbox in their default. │
│ │
│ Delivery method for local mail: │
│ │
│ mbox format in /var/mail/ │
│ Maildir format in home directory │
│ │
│ │
│ <Ok> <Cancel>
--------------------------------------------------------------------------------
mbox format in /var/mail/
--------------------------------------------------------------------------------
The Debian exim4 packages can either use 'unsplit configuration', a │
│ single monolithic file (/etc/exim4/exim4.conf.template) or 'split │
│ configuration', where the actual Exim configuration files are built from │
│ about 50 smaller files in /etc/exim4/conf.d/. │
│ │
│ Unsplit configuration is better suited for large modifications and is │
│ generally more stable, whereas split configuration offers a comfortable │
│ way to make smaller modifications but is more fragile and might break if │
│ modified carelessly. │
│ │
│ A more detailed discussion of split and unsplit configuration can be │
│ found in the Debian-specific README files in /usr/share/doc/exim4-base. │
│ │
│ Split configuration into small files? │
│ │
│ <Yes> <No> │
--------------------------------------------------------------------------------
No
