Generically, things like msmtp tend to be called 'nullmailers', after an
early example of the type.  I try to track the known options, here:

If this is a cron job running on your local machine then rather than
having to fully comnfigure your MTA to send acceptable emails to gmail
(i.e. static ip, spf, dkim, etcetera) it would be simpler to enable
local delivery to your local email account. You can then just read this
by setting up an account in Thunderbird (it's a mbox file so use the
spool option) and it will remain segregated from your gmail.


I came to this conclusion, too, but, so far, have been unable to get 
local delivery working, either.  I have tried running 'maIl marc' then 
filled in subject and body, then ended with CTL-D.  Is CTL-D the correct 
way to end the message and send the e-mail?  Is there something else 
that I need to do to actually send the message?   It may be that the 
various things that I have tried have borked local delivery.  What 
should I have installed and how should it be configured to deliver mail 
to my local user?


Clearly, I am doing something wrong, I just don't know what.


Marc


Rather than redirect the cron mail output I just let root user jobs go
to the default root account and alias that to my local email account
(using /etc/aliases and the newalliases command).

This will then also pick up any other root jobs that generate emails
(in my case unattended-upgrades of security updates, and failed
logins).

_And_ unless you turn off apparmor. Sorry if this is obvious.

But I concur with the recemmendation of msmtp. A full MTA like exim is
definitely overkill in this situation.

'msmtp' is a lightweight and simple option for sending messages to remote smtp 
servers from shell scripts. with a variable (e.g. "$mailcmd") it can be used as 
drop in replacement for mailx.

msmtp works well for these type of things.  

Beware though as the package includes an apparmor profile which can cause 
problems

if you don't use the defaults.



Don't ask me how I know this.

The linked to article doesn't seem to mention adding credentials for
the smarthost. You add them in:

/etc/exim4/passwd.client

See if that helps.

Are you sure that your exim4 mta has not been simply denied access by
Google because it has no static ip, spf, dkim etcetera? An alternative
would be to use your isp smtp-server by configuring it as a smarthost
like in this example

I tried running "dpkg-reconfigure exim4-config".  I selected "Mail sent 
by smarthost; no local mail" and then took all of the defaults.  I then 
tried to send a test e-mail using the command shown in the link you

Thunderbird that I am running, but no e-mail gets through to my account.

[DNG] Configuring cron and exim4 to send e-mail after running cronjob

I use Thunderbird for e-mail, so I have never bothered with configuring

I have a few lines in root's crontab to do periodic backups and I would 
like to receive an e-mail when the job is completed.  I have added a 
MAILTO line to my crontab with my gmail address.  The job runs, the 
backup is created, but I do not receive any e-mail from cron.  I am 
assuming that I need to run dpkg-reconfigure on exim4-config, but I 
don't want to mess up my e-mail that is going through Thunderbird.
