mailgun to email address replaced by cc email address

Question

I have an issue with mailgun when send an email with cc param. But when I execute the method, I have got wrong header from cc email.

This is my code

var client = new RestClient
{
    BaseUrl = new Uri("https://api.mailgun.net/v3"),
    Authenticator = new HttpBasicAuthenticator("api", "secret-key")
};

var request = new RestRequest();
request.AddParameter("to", "[email protected]");
request.AddParameter("cc", "[email protected]");
client.Execute(request)

So, Can anyone please help me to resolve this?

This is information from email to

This is what I get from cc Email

Answer 1

Hm, I can't reproduce your problem. I'm getting the same mail message in both to and cc mailboxes with correct addresses. Here is a screen from cc mailbox:

To proceed with the problem, could you please do the following:

1. Update your question with the exact code you use for calling netgun API. Little things matter here and we should understand what makes difference between your and my calls.

2. Could you also please update your question with raw mail message got to cc mailbox. In gmail you could do it by clicking down arrow near reply button and selecting "Show original":

There will be a bunch of different headers in the message including to and cc:

Please share with us the whole mail packet you get.

3. If possible, please check the issue with mail address not on gmail. It works ok for me on gmail but may be in your case it's the root cause of message modification.

Answer 2

Please add a request.Method = Method.POST; in your code, because according to official C# mailgun api documentation.

Could you try this code (with the same order) :

    RestClient client = new RestClient ();
    client.BaseUrl = new Uri ("https://api.mailgun.net/v3");
    client.Authenticator =
        new HttpBasicAuthenticator ("api",
                                    "YOUR_API_KEY");
    RestRequest request = new RestRequest ();
    request.AddParameter ("domain", "YOUR_DOMAIN_NAME", ParameterType.UrlSegment);
    request.Resource = "{domain}/messages";
    request.AddParameter ("from", "Email From <[email protected]>");
    request.AddParameter ("to", "[email protected]");
    request.AddParameter ("cc", "[email protected]");
    request.AddParameter ("subject", "Email Subject");
    request.AddParameter ("text", "Testing some Mailgun awesomness!");
    request.AddParameter ("o:tracking", false);
    request.Method = Method.POST;
    return client.Execute (request);
