Notify email without autentication

[maxdo]

Hi,
on my NAS, would i like to active the notify by email.
in the menu i can configure Server and port, but MUST configure the user and password too.
My provider auth my connection SMTP by ip addres, and doesn't require authentication U/P.

I had try to remove the configuration of user and password, but the System ask me tu put, because need.

how can i fix?

a other question it is how can i custome the FROM addres ofthe email? in the notify menu i don't see a fild for have that.
thanks

My provider auth my connection SMTP by ip addres

That would mean you can send email only from your home and not for example from your smartphone connected to internet (which may use any IP)!

Currently notification feature can not work as you expect and requires to use an authentication step.

a other question it is how can i custome the FROM addres ofthe email? in the notify menu i don't see a fild for have that.

FROM field is always the account used to authenticate. As you do not have this step it will be an issue.

To work as you want I need to make some change and some outputs from your attempt.

I assume your NAS is behind the wanted public IP, then open a shell terminal and run this command:

Code: Select all

telnet yoursmtp.domain 25     

(if your provider uses an insecure smtp server) otherwise run

Code: Select all

openssl s_client -starttls smtp -connect yoursmtp.domain:PORT

PORT may be usually 25, 465 or 587 keep or remove the starttls option if it is required by your smtp server.

Then need to send the HELO command, may be in your case you should send a determined data. So try your IP or yoursmtp.com

Code: Select all

ehlo yoursmtp.domain

or

Code: Select all

ehlo your.authorized.IP

(it is really 'ehlo'). Then some responses should happen.

Please to paste all of them

§Hi jocko,
sorry me, but i completly forgot to have submit in past a similar request.
however, stil lthe issue with the other sMTP vodefone smtp.vodafone.net.au.
i think that the your firmware try to auth the send out email. however, becasue i can't leave blanck the field User and password.
so submit the request email sent, with that credentail however (i put a point in both field, to compalince the configuration form)
So, there no way to use a request smtp out withou credential?
many htnaks.
ciao
:thinking

Note: you have perfeclty right when said that use a smtp withou a u/p it is out security....but Vodafone thing in different way :woohoo

Hi

We go to test if by disabling the auth command is enough when openssl is connect to your smtp server. please to note EHLO command uses as IP your public IP (WAN IP).

So get the package from your pm and store it in fvdw share.
Uncompress it

Code: Select all

tar -xf /direct-usb/fvdw/mail2.tgz

set run permissions

Code: Select all

chmod a+x /direct-usb/fvdw/mail2

On the notification menu, use as login the keyword "disabled" and any password string. Save your change but do not use the test button.

So now run a test like this

Code: Select all

 echo -e "This is a test\n without authentication! ...\n"|/direct-usb/fvdw/mail2 -s 'vodafone smtp test' any.receiver@address.com

where "any.receiver@address.com" is a valid email address where you can check if you receive the test email. it can be the email address to deliver system messages set on notification menu.

Please to post the output (of course you will have to hide your public IP...)

Note: if it does not work, you will have to use another email free server provider where authentication is required by creating a free account and then to use this account for relaying the notification to the deliver system address

subject=SMTP SVR
to=supporto@MYDOMAIN
mode=1

Hi

So I think this is the easiest way to fix your issue :

Note: if it does not work, you will have to use another email free server provider where authentication is required by creating a free account and then to use this account for relaying the notification to the deliver system address

and you can keep your vodafone address as system address.
