system email alerts sent to gmail address?

[jfaberna]

I have ssmtp setup on my system so I can get crontab alerts sent to my gmail address. I actually have 2 gmail address, one I created for the computer to use to sent messages and one is my regular email to receive these alerts. I followed the instructions below:

https://help.ubuntu.com/community/EmailAlerts

I'm getting the daily alerts correctly, but mail sent to root from the system, like smartd do not get sent to me. Instead I get a Delivery Status Notification (Failure) from gmail to the email address setup for the computer to send out the alerts.

Any idea on how to fix this?

Remote servers can only send mail to fully-qualified domain names like mail.example.com. If you have a domain, use that, not "mythbuntu."

You could try using as an alternative the To address

you@[10.10.10.10]

with your machine's IP address substituted for 10.10.10.10.

GMail is pretty picky so I can't promise it would work.

The point is my server is sending mail to my personal account. I've setup cron to do it and some SQL database maintenance stuff. I get those emails. The problem is other system functions like smartd send emails to root@mythbuntu.

If I can't forward all mail to root to my personal address, I'll have to figure out each system daemon that sends mail to root and change that address.

[SeijiSensei]

Add an entry to /etc/aliases that points root to your email address.

root:     me@example.com

Then run the "newaliases" command. Note the colon after "root".

Gmail wants you to send FROM a real domain too. They have lots of rules to prevent spam and malware. There are instructions with gmail to configure your systems, can't really remember much of it but years ago when I did it we had to add a bunch of extra records to the company's dns.

Unfortunately, newaliases isn't used by ssmtp

jim@mythbuntu:~$ sudo newaliases
newaliases: Aliases are not used in sSMTP

I have my server sending mail as an gmail user to other gmail accounts. That's not the problem. I can't seem to get my sSMTP setup to forward internal mail sent to 'root' forwarded to a gmail account.

I only use sendmail or postfix, so I can't help with that.

[jfaberna]

So how difficult is it to install and use sendmail or postfix? Can I install it over sSMTP?

[SeijiSensei]

It might remove ssmtp. I know that's true for sendmail or Postfix when the other is installed. Do a backup first.
