I was testing MailKit with Fetch on the mail Envelope. summary.Envelope.From[0] gave an exception after getting emails from the mail server. On inspection, the From field is shown on the original mail file as:
...
...
From: Root User <>
...
Gmail shows this mail as (unknown sender)
I can attach the header if necessary. Is there a standard way to deal with this?
Yes, you can do what GMail does which is effectively:
if (summary.Envelope.From.Count == 0)
return "(unknown sender)";

I am having issues with mail bouncing when sending from my own server to my own active yahoo account using JavaMail. The mails are passing SPF, DKIM and DMARC according to google mail that receives the same messages being bounced by yahoo. I can send messages from other accounts to my yahoo account without issue.
The messages send fine from my server to ZMail, GMail, Microsoft mail. Looking at the emails, the only thing that I have noticed is the message header for the Message-Id. My messages have the following header:
Message-ID: <923936395.17.1634776639078#[internally visible hostname]>
I am wondering if this header could be the problem and whether there is a way in JavaMail or in the Apache James to set the hostname or IP address that gets used in this message so that rather than using the "internally visible hostname", I can get the hostname that is externally visible. I have been searching the available documentation for Apache James and JavaMail but have not found any parameters to try in order to resolve this.
According to the Decompiled SRC of sun mail it should be possible by setting some properties for your session.
props.setProperty("mail.from", user);
props.setProperty("mail.host", host);
//props.setProperty("mail.user", user);
The Id will be updated by the save method (saveChanges()) and will trigger an new ID generation (updateHeaders() -> updateMessageID()). (Looked up in the decompiled MimeMessage.class)
Leading to the HostPart called in javax.mail.internet.InternetAddress.
The relevant method is _getLocalAddress.
Here you can see that the values get extracted from the Properties or will fallback to your local machine.
Used Fields:
user.name
mail.from
mail.user
mail.host
The user.name property can also be looked up from the system props.
My app is using linkedin as oauthd login method. For some of users there is no valid response when I'm trying to fetch email address (https://learn.microsoft.com/en-us/linkedin/shared/references/fields/basic-profile#email-fields)
Request:
GET https://api.linkedin.com/v2/emailAddress?q=members&projection=(elements*(handle~))
Response:
200 {"elements":[]}
^^^ missing email field
200 {"elements":[{"handle":"urn:li:emailAddress:472511033","handle!":{"message":"Downstream service returned an empty response for URN.","status":404}}]}
OK, but failed?
Normal response looks like this:
200 {"elements":[{"handle~":{"emailAddress":"XXX#XXX"},"handle":"urn:li:emailAddress:XXX"}]}
Is there any settings in linkedin profile that blocks requesting emailAddress?
I found in documentation that this is related to new users that was registered using phone.
The API call would return empty response body if the authenticated user was registered via phone number, and never added any primary email address into their LinkedIn account previously. The value of type is case sensitive, and can only be EMAIL in this case.

I have been trying to get push notifications working using firebase. So far I have got as far as successfully sending an empty message "tickle". The problem is adding the message payload seems to have no affect on what the client receives. That is the service worker just sees it as another empty message.
I started by going through googles guide here - https://developers.google.com/web/ilt/pwa/introduction-to-push-notifications
After going through how to send an empty message it says the message payload must be encrypted and suggests using an existing library to do it. To quote - "As with anything related to encryption, it's usually easier to use an actively maintained library than to write your own code".
I tried to use web-push-php which is one of the libraries recommended by googles guide. After having trouble with that i discovered web-php-push doesn't actually support firebase.
Looking on here i find examples that look really simple and don't event encrypt the message payload. It is simply sent in plain json. Doing this has no affect and the receiving end still thinks it's an empty message. See my code below.
I am at a complete loss with this and i'm confused why googles guide says the message data must be encrypted but there are countless examples on SO where it is just send in plain json text.
This is what i am posting from my server to the end point.
POST https://fcm.googleapis.com/fcm/send Authorization: key=[my server
key] Content-Type: application/json {"priority":10,"to":"[subscriber
id]","notification":{"body":"test body","title":"test title"}}
Here is my event listener in my service-worker.js
self.addEventListener('push', function(e) {
var body;
if (e.data) {
body = e.data.text();
} else {
body = "No message "+JSON.stringify(e);
}
var options = {
body: body
};
e.waitUntil(
self.registration.showNotification('Launtel Residential', options)
);
});
When i run the post request above the push notification occurs and triggers the service worker 'push' event as expected but no message data is present. e.data returns null. The 'e' object always just contains a flag set to true. e.isTrusted==true
I am building a Windows Phone 8.1 application and want to add push notifications from Windows Azure. I am creating the channel by using CreatePushNotificationChannelForApplicationAsync, after which I take the resulting URI and store it in the Azure database. When trying to send a push notification by using push.wns.sendToastText01, I get the following error in the Azure logs:
Error in script '/table/Message.insert.js'. Error: 400 - An invalid tag 'https://db3.notify.windows.com/?token=AwYAAAC3tTi3W5ItZ0hWdZ3FLmELt%2flHcwpsM...' was supplied. Valid tag characters are alphanumeric, _, #, -, ., : and #.
I noticed that the channel URI contains the '%' which does not appear among the valid characters, yet that is the URI that gets generated in the client application. Am I using a wrong method for sending push notifications or is there something else I am missing?
Edit: I am using Node.js for backend in Azure.
request.execute({
success: function() {
push.wns.sendToastText01(channelUri, {
text1: "Google Plus Friend Tracker",
text2: item.content,
param: '/ChatPage.xaml?friendGoogleId=' + item.author_id
})
}
});
Looking at the wns object documentation, the first parameter would be the tags that you are sending to. Since you're providing a channel in the code above, you are getting the error specified.
The backend does not need to provide the channel URI, as this was associated with the Notification Hub via the client-side registration action. If you are broadcasting the message, you would just provide null as the tag value. Otherwise, you can use the tags that were specified when you registered the channel URI.
For more about the process, see the "Get started with push" tutorial. There is also an example of using a tag (user ID) in the "Send push notifications to authenticated users" tutorial. For more on tags in general, the Notification Hubs breaking news tutorial is also good.
I'm trying to send verification mail but it showing some error
my error is URI malformed
First,error screenshot
I added email package and at the server side i added something like
Accounts.config({
sendVerificationEmail:true
});
i set env_url like this
process.env.MAIL_URL = 'smtp://postmaster%sandbox.mailgun.password#smtp.mailgun.org:587';
URIs use percent encoding for reserved characters, and a % by itself is invalid. Also, there should be a : between the username and the password (see the docs). This should be the format you want:
'smtp://postmaster%40sandbox.mailgun:password#smtp.mailgun.org:587'
which decodes to:
'smtp://postmaster#sandbox.mailgun:password#smtp.mailgun.org:587'
