Send email from shell

[Scrat]

Oh Yeah! That's why it doesn't work for you!
Surfing the web I read from many sources that from release 8.0.1b3 there is some problem sending mail with TLS and SSL....

Switch back to 8.0! :D

For me on FN 8.0.1 b4 it's running fine without any problems (see my configuration in my post above). But I must admit, I don't care of the GUI and the testmail of the GUI. For me it's important that I can send mails from a script. :)

YES! As already reported in my previous post! ;)

Ok, well I tried again like Lucas did, set my port to 587 and the test email from the GUI failed again... BUT, I tried the script again with the port left at 587 and it worked!

Peter, you're right, I'd rather have it work from the shell instead of it just politely telling that the test message worked and never getting anything when there's a problem. Hopefully in the *near* future it will work correctly both ways!

Thanks to both of you for helping to get this working!

Note: This also works (of course without the subject)-

some command, lets say dmesg

dmesg | msmtp -a default myusername@gmail.com

Lucas, I would recommend you use 'zpool status -v' with your script. It gives you more details about which drive is degraded.

No email field!

Houston we have a problem... no email field on my UI.

 

[ProtoSD]

Tekkie, that's strange, have you tried another browser?

Anyway, you don't need to change email for admin, just root should work fine.

I'm working on an improved script to also check smart status. I'll post it here when I'm done.

 

[Tekkie]

I tried, Opera, Chrome and IE9 none show the email box :(

Where do I change the email address for root?

 

[ProtoSD]

Left sidebar click Users - View All Users
Look for root on the right side and click "Change E-mail" button

 

[Tekkie]

Left sidebar click Users - View All Users
Look for root on the right side and click "Change E-mail" button

Not there either, I can only modify the email of users that I created myself, my installation is a clean 8.0.1-B4 i.e. no upgrade from B3.

 

[ProtoSD]

Tekkie, I'm usually the one with the weird problems, are you trying to take away my mojo?? ;)

I just booted my clean beta 4 virtual machine and it was there.
Here's a screen shot just in case you're having tunnel vision, or maybe not...

I will put on my special glasses this weekend and take a look once more...

BTW, I can confirm, the mail field is there both for 8.0 and 8.0.1-B4, using Firefox 6.0 ;)

With ultra special x-ray glasses I did find the option.... :)

Well, my goal is code a simple bash script to check some system parameters and expecially disk state, and send them via mail. That's why I would like to know how to send mail using bash in non interactive mode.

I got my email to work, even with weird error messages in the UI and now I get emails on a daily basis with this info:

What is it that you want to have in the email that's not in this?

 

[ProtoSD]

Yeah, I started getting those now too, but a warning.... If you accidently type your password for your username it gets sent in clear text in that email! Not very good. I might open a ticket for that.

I'm almost ready to post my drive failure detection script with email warning. Of course it'll probably be useless after they fix things they way they should be.... but in the meantime.

 

[dumbbell]

This is the mail config setup by GUI:

Code:

freenas# cat /usr/local/etc/msmtprc
...
port 25
...
tls on
...
tls_starttls off
...

I think there's a bug in /etc/rc.d/ix-msmtp, the script that generates this "msmtprc". It checks if the port number equals 25 and sets tls_starttls to "off" (port == 25) or "on" (port != 25). I think it should be reversed: use STARTTLS when the port is 25 and plain SSL when using 465.

Concerning port 587, I think the behaviour should be the same than 25 ("tls_starttls on") but I'm really not sure because I never encountered this port.

I had a similar problem than yours, Lucas, and setting "tls_starttls" to "off" resolved it.

Edit: The ticket #528 talks about this issue I think.

Now you've done it!

Now you guys have really done it!!
My working email now does not.
All I did was read your posts.
Haven't even touched my email configurations, or any other configurations at all!
Not even a reboot!
Damn!
What ever you guys are thinking of fixing next, Please Don't!

:p

Hello,
Now that msmtp has been removed from FreeNAS, could you give me a way to send emails from shell to external accounts (gmail...)?
Thanks in advance :)

The following will work in both FreeNAS 0.7 and FreeNAS 8.0.1:

Code:

#!/bin/bash

FROM=me@mydomain.com
TO=me@mydomain.com
SUBJECT="`hostname`: Test Email"
BODY=""

PRINTF=/usr/bin/printf
MSMTP=/usr/local/bin/msmtp
MSMTPCONF=/var/etc/msmtp.conf
#...
BODY="Something"
#...
# Send email in FreeNAS 0.7.x
[   -f $MSMTP ] && $PRINTF "From:$FROM\nTo:$TO\nSubject:$SUBJECT\n\n$BODY" | $MSMTP --file=$MSMTPCONF -t
# Send email in FreeNAS 8.0.1+
[ ! -f $MSMTP ] && $PRINTF "$BODY" | mail -s "$SUBJECT" $TO
