I am trying to send news to clients, through a specific Data Feeder. The news are in UTF-8 format, and they can only be sent to the clients that their platform can show them.
So, my question is there any way of sending the news only to these clients? The NewsSend() method of the MT4ManagerAPI sends the news to all the clients. I just want to send the news to clients with a specific language set in the terminal or, at least, to a specific group only.
Thank you
you would have to create a manger that only sees that particular group of users. Then I believe, if you log in with that manger to the api, the connection will only be able to interact with these users. If you NewsSend on that connection only those users should see it.

I'm trying to run an MQTT broker and I want to store the published data, but I need to know which user sent the message so I can store payload for each user and study them later. The problem is when two different user try to publish message on same topic I can not tell whose data it is. Is there a way to figure out the publisher of a message? I'm using Mosquitto btw.
Short answer, you don't.
MQTT messages do not contain any information about the user or client that sent it, unless you choose to encode it in the message (as part of the payload for v3.x or alternatively in the header properties for v5.0)
Longer answer:
Some MQTT brokers have plugin APIs that may allow you access to more meta data for a message. You may be able to write a plugin that will take the message + the meta data and then store them. Last time I looked, mosquitto's plugin API was only for writing authentication plugins, and did not give access to the messages themselves. But a different broker may allow this.
I am creating a service in which services can upload files from different methods.
One of them is by sending the file to a specific email address that is linked to the app.
I have managed to do so with a unique email address that is the same for all the users (generic#mail.com), but I would like that have a different address for every user (like user_specific_email#mail.com).
I am using MailBox on rails.
Do you know if it is possible ? And if so, is it more secured and generates less risks of bottleneck if a lot of mails are processed at the same time ?

I'm working on the front end development of a custom mail system and at this point I've been using simple HTML to display data based upon my own received e-mails, however now I would like to create a table in my database of the information which is received upon connecting from on POP3/iPOP server.
Using Outlook.com you can rigth-click a mail and view source however I am oblivious to as whether this is the information gathered upon connecting.
I'm hoping this is the sort of question I can ask on here, basically I'd like to have an answer showing one example of all information received from the iPOP/POP3 server with information and/or useful resources.
To Clarify
I'm working on the front-end development and would like realistic information that would be gathered to create a dummy database table, thus meaning I can echo the information and create functions and whatnot prior actually establishing a connection to POP3 or iMAP
POP is a classic internet protocol in that it contains lots of plain text. You can use POP effectively using just telnet server.doma.in 110 to see how a server responsds to a particular command, and Wireshark will dump the commands user by Outlook and the server's responses, both in a format that'll suit your tests well.
With my rails application, I'm supposed to provide following features:
There a limited number of users interacting with my system (in order of 10 to 20)
Like any normal mail client users should be able to have an inbox page showing received message, response to individual email and etc....
The mail client part cannot be an external application, they want everything packaged into a single application!
Normally These emails should be stored for future use
In order to send a receive email, we do not need to setup a mail server. They will provide the server and we will fetch the message with POP3 or something else. Same goes for sending emails.
The application itself often needs to look into these message as well, so it should be able to access corresponding email objects.
Separate part of these applications can be handled with individual gems such as Mailman, ActionMailer, and etc...
But what would be your suggestions to get this done?
I suggestion customizing an open source solution according to your needs. This is a gem/project that you should look at https://github.com/mailboxer/mailboxer It has all the features that you mentioned and its straightforward in its customizations.
tl;dr What's the "right" way to get my data off an iPad such that only a researcher can receive and read it?
Full Explanation:
In my app, I've got to get the data from a database off the app and to a researcher. This will consist (most likely) of two separate files. The first will be table of identifying information:
ID FirstName ... etc.
This is sensitive identifying information that has to be sent so that only the researcher can get it.
The other will be de-identified info that uses ID numbers and the like, and it doesn't necessarily have to be secure, but I would like to only have it go to the researcher, obviously.
So far, I've only ever worked with data that can just be emailed, but there are some problems with this implementation. You can't just up and send an email; you can only present an email composition view ready to send, and then the user can edit the email before sending it. So a user could send this data to someone else.
Another wrench in the works: this researcher doesn't have access to a server, so I can't do SFTP uploads that way. It's also not guaranteed that the app will have internet access all the time.
The best idea I've got so far is to have a button to compose an email that attaches an encrypted file, protected by a password whose hash is hard-coded, I mean, compile-time provisioned, into the app.
EDIT: Here's what I'm going to do for the time being: use some personal server space so I can implement SFTP uploading, and then I will work with the researcher to get some server space they can use. Thanks for your answers.
Email is not particularly "safe" but if you just want to send email to one specific address, without the possibility of user intervening, you can use SMTP protocol yourself.
In one of my old apps I used skpsmtpmessage - I don't know if it still works, but if not there should be more solutions like it.
What it does is basically send email messages programatically, without using the composer dialog.
