Hi,

Yes, it can be done configuring Exim to send emails to external
domains using a smarthost.

1.- Configure properly /etc/aliases and add a default user to receive
emails. For example

# /etc/aliases
mailer-daemon: postmaster
postmaster: root
nobody: root
hostmaster: root
usenet: root
news: root
webmaster: root
www: root
ftp: root
abuse: root
noc: root
security: root
root: youruser
youruser; redalert.commander@gmail.com

2.- Configure exim4 to send emails using a external smarthost. As I
can see you have a gmail account. I have the same configuration in my
servers.

Modify your update-exim4.conf.conf and update the dc_smarthost variable:
dc_smarthost='smtp.gmail.com::587'

Create the /etc/exim4/passwd.client with the right permission
-rw-r----- 1 root Debian-exim 401 abr 21 21:20 passwd.client

And add the following:
# password file used when the local exim is authenticating to a remote
# host as a client.
#
# see exim4_passwd_client(5) for more documentation
#
# Example:
### target.mail.server.example:loginassword
*.google.com:redalert.commander@gmail.comassword
gmail-smtp.l.google.com:redalert.commander@gmail.comas sword
*.google.com:redalert.commander@gmail.comassword
smtp.gmail.com:redalert.commander@gmail.comasswo rd

3.- Restart the exim4 daemon

Have fun!

Regards

Juan

You can set up an alias for root in /etc/aliases to point to another
host. Then all email to root will forward to the other address.

root: root@other.example.com

Normally after changing the aliases file you need to run 'newaliases'
to rebuild the cache file. But I think exim does not need this.

Alternatively if you only want to change the crontab output and
nothing else then Vixie Cron (the default for most GNU/Linux distros)
enables you to set the MAILTO variable. If your system has a default
install of exim then very likely you can simply set the address. Put
this in your crontab file and it will only affect that particular
crontab.

MAILTO = "root@other.example.com"

But of course exim4 in a default configuration is an email server even
if you are not thinking of it that way.

The other suggestion to use nullmailer to simplify the MTA seems
reasonable to me. I always use nullmailer for chroots.

The other suggestion to reconfigure exim to use a smarthost is
reasonable too. But I think probably more complicated than you need
to do for what you are asking.

It seems you forgot to mention I need to run update-exim4.conf?
But I figured that out.

Thanks, works like a charm when using gmail
Unfortunately I was trying to get it working with a different e-mail
address, one I have with my ISP, yet this didn't work out. When using
that one I got frozen message in the exim queues and a message in the
exim log saying my ISP's smtp rejected the message as unroutable.

But I settled for the gmail solution instead, so I'm satisfied.

Thank you very much.

Kind regards,
Steven

Unfortunately both of these solutions don't work with my default exim
config, as that won't allow you to send to external addresses. The exim
config would need to be changed anyway.

I have no experience with nullmailer whatsoever (but none with exim
either), but as it's a separate package I needed to install, and would
need to lookup the config, I figured Juan's exim solution would be the
easiest for me.

It does the job for me, and isn't terribly complicated, Juan explained
it exactly as needed.

Thanks everyone for helping me out on this one.
