I can send emails with SMTP option in .Net but I need to use .NET SDK to send emails via Amazon. It gives me error that says "Email address is not verified", event though I am sure that it is verified. By the way, I am using a Test Account(SandBox).
What am I doing wrong? or am I missing anything?
here is my code,
var sesClient = new AmazonSimpleEmailServiceClient("AKIAJHXXXXXXXXXXX", "RVGdbCKXILwjUIKSexKlwXXXXXXXXXXXX",Amazon.RegionEndpoint.USEast1);
var dest = new Destination
{
ToAddresses = new List<string>() { "tayfun.ural#aryxxx.com" },
CcAddresses = new List<string>() { "arif.yilmaz#aryxxx.com" }
};
var from = "tayfun.ural#aryxxx.com";
var subject = new Content("You're invited to the meeting");
var body = new Body(new Content("Please join us Monday at 7:00 PM."));
var msg = new Message(subject, body);
var request = new SendEmailRequest
{
Destination = dest,
Message = msg,
Source = from
};
var verify = sesClient.VerifyEmailAddress(new VerifyEmailAddressRequest { EmailAddress = "tayfun.ural#aryada.com" });
try
{
var response = sesClient.SendEmail(request);
}
catch (Exception ex)
{
throw ex;
}
When using Amazon SES in sandbox/test mode, all from/to/cc addresses must be verified email addresses. The error "Email address is not verified" means that atleast one of the email addresses is not verified. It could be the TO, FROM, CC, or BCC.
In your case, ensure that both "tayfun.ural#aryxxx.com" and "arif.yilmaz#aryxxx.com" are verified and/or that "aryxxx.com" is a verified domain.
String FROM = "SENDER#EXAMPLE.COM"; // Replace with your "From" address. This address must be verified.
String TO = "RECIPIENT#EXAMPLE.COM"; // Replace with a "To" address. If you have not yet requested
// production access, this address must be verified.
String SUBJECT = "Amazon SES test (AWS SDK for .NET)";
String BODY = "This email was sent through Amazon SES by using the AWS SDK for .NET.";
// Construct an object to contain the recipient address.
Destination destination = new Destination();
destination.ToAddresses = (new List<string>() { TO });
// Create the subject and body of the message.
Content subject = new Content(SUBJECT);
Content textBody = new Content(BODY);
Body body = new Body(textBody);
// Create a message with the specified subject and body.
Message message = new Message(subject, body);
// Assemble the email.
SendEmailRequest request = new SendEmailRequest(FROM, destination, message);
// Choose the AWS region of the Amazon SES endpoint you want to connect to. Note that your production
// access status, sending limits, and Amazon SES identity-related settings are specific to a given
// AWS region, so be sure to select an AWS region in which you set up Amazon SES. Here, we are using
// the US East (N. Virginia) region. Examples of other regions that Amazon SES supports are USWest2
// and EUWest1. For a complete list, see http://docs.aws.amazon.com/ses/latest/DeveloperGuide/regions.html
Amazon.RegionEndpoint REGION = Amazon.RegionEndpoint.USEast1;
// Instantiate an Amazon SES client, which will make the service call.
AmazonSimpleEmailServiceClient client = new AmazonSimpleEmailServiceClient(REGION);
// Send the email.
try
{
//("Attempting to send an email through Amazon SES by using the AWS SDK for .NET...");
client.SendEmail(request);
//("Email sent!");
}
catch (Exception ex)
{
//("The email was not sent.");
//("Error message: " + ex.Message);

I registered a daemon app in Azure AD and am creating a class to do some basic things like send and delete emails but I get an error when trying to send between two #*.onmicrosoft.com email boxes. I am able to send from Gmail to these emails for example but not between the two emails for some reason.
Error:
The way I am sending emails is as follows:
public async Task Send(string[] to, string subject, string body, FileInfo[] attachments = null, bool saveToSentItems = true, bool isBodyHTML = false)
{
var msg = new Message
{
Subject = subject,
Body = new ItemBody { ContentType = (isBodyHTML) ? BodyType.Html : BodyType.Text, Content = body },
ToRecipients = to.ToList().Select(x => new Recipient() { EmailAddress = new EmailAddress { Address = x } })
};
await graphClient.Users[email].SendMail(msg, saveToSentItems).Request().PostAsync();
}
So I think it's because of trial licenses and couldn't figure out way yet to turn off the IP filtering:
I am having an issue with SmtpClient in an ASP.NET web application.
I have a generic function that builds an email message and then sends it. The code is as follows:
public static bool SendMessage( string fromName, string toName, string subject, string body ) {
var smtpClient = new SmtpClient("server address here")
{
Port = 587,
Credentials = new NetworkCredential("user", "pass"),
EnableSsl = false,
};
var mailMessage = new MailMessage
{
From = new MailAddress("sender", "Testing"),
Subject = subject,
Body = body
};
mailMessage.To.Add ( new MailAddress(toName, "Valued Customer") );
try {
smtpClient.Send ( mailMessage );
return true;
}
catch (Exception ex) {
var error = $"ERROR :{ex.Message}";
return false;
}
}
The problem is, I get the following error when I call it:
Mailbox unavailable. The server response was: <email address being sent to> No such user here
Naturally I removed the value in the < >, but in the original error message it is the email address of the recipient. I almost think the SMTP server believes the recipient has to be a user on the system.
What can I try next? I even hard-coded email addresses in rather than using variables, thinking maybe there was some weird issue with that, but it didn't work.
The error is telling you that the the SMTP server does not have a user with that email address (usually it has to do with security around the FROM address). The SMTP server will not send email if it does not recognize the FROM address.
Solution, change your FROM. Example:
var mailMessage = new MailMessage
{
From = new MailAddress("tester", "test#adminsystem.com"),
Subject = subject,
Body = body
};
I've been working with Microsoft graph API to receive and reply to the mail.
I've successfully received and send mails, but as per Graph API docs in reply only a comment can be passed.
https://learn.microsoft.com/en-us/graph/api/message-createreply?view=graph-rest-1.0&tabs=cs
I've developed the send mail code as shown below:-
IList<Recipient> messageToList = new List<Recipient>();
User currentUser = client.Me.Request().GetAsync().Result;
Recipient currentUserRecipient = new Recipient();
EmailAddress currentUserEmailAdress = new EmailAddress();
EmailAddress recepientUserEmailAdress = new EmailAddress();
currentUserEmailAdress.Address = currentUser.UserPrincipalName;
currentUserEmailAdress.Name = currentUser.DisplayName;
messageToList.Add(currentUserRecipient);
try
{
ItemBody messageBody = new ItemBody();
messageBody.Content = "A sample message from Ashish";
messageBody.ContentType = BodyType.Text;
Message newMessage = new Message();
newMessage.Subject = "\nSample Mail From Ashish.";
newMessage.ToRecipients = messageToList;
newMessage.CcRecipients = new List<Recipient>()
{
new Recipient
{
EmailAddress = new EmailAddress
{
Address = "abc.xyz#xxxx.com"
}
}
};
newMessage.Body = messageBody;
client.Me.SendMail(newMessage, true).Request().PostAsync();
Console.WriteLine("\nMail sent to {0}", currentUser.DisplayName);
}
catch (Exception)
{
Console.WriteLine("\nUnexpected Error attempting to send an email");
throw;
}
This code is working fine!!
Can someone please share how I can Reply to a mail with attachment and mailbody like I'm able to do in Send mail.
Thanks in advance.
You have to create a reply, add the attachment, and then send the message. With the basic basic /reply endpoint you cant do it.
E.g.:
Create the message draft using POST request
As a response you will get the whole message structure with id set to something like AQMkADAwATMwMAItMTJkYi03YjFjLTAwAi0wMAoARgAAA_hRKmxc6QpJks9QJkO5R50HAP6mz4np5UJHkvaxWZjGproAAAIBDwAAAP6mz4np5UJHkvaxWZjGproAAAAUZT2jAAAA. Lets refer to it as {messageID}.
After that you can create an attachment using POST request to https://graph.microsoft.com/beta/me/messages/{messageID}/attachments
-After step 2 you will see created message in your mailbox Drafts folder. To send it use https://graph.microsoft.com/beta/me/messages/{messageID}/send
Hope it helps.
When I send an email using AWS SES in a C# application the email names don't show in the received email - only the email addresses show.
The from/to emails I've added are strings in the form " Their Name". It's clearly understanding that as it's sending it to the right place, but just stripping out the names.
internal void SendEmail()
{
try
{
// Construct an object to contain the recipient address.
Destination destination = new Destination();
destination.ToAddresses = toList;
if (ccList.Count > 0) destination.CcAddresses = ccList;
if (bccList.Count > 0) destination.BccAddresses = bccList;
// Create the subject and body of the message.
Body bodyobj = new Body();
if(body!=null) bodyobj.Text = new Content(body);
if(html!=null) bodyobj.Html = new Content(html);
// Create a message with the specified subject and body.
Message message = new Message(new Content(subject), bodyobj);
// Assemble the email.
SendEmailRequest request = new SendEmailRequest();
request.Destination = destination;
request.Message = message;
request.Source = from;
AmazonSimpleEmailServiceClient client = new AmazonSimpleEmailServiceClient(Amazon.RegionEndpoint.EUWest1);
SendEmailResponse ser = client.SendEmail(request);
sent=true;
}
catch (Exception e)
{
errmsg = e.Message;
}
}
You can provide recipients with names in the standard email format
Fred Bloggs <fred.bloggs#exmaple.com>
If you specify your ToAddresses as a list of strings of that format, the name will be set properly.
This conforms to the Internet Message Format (rfc5322) spec. See section 3.4.
I'm trying to send an email with the Office 365 C# client library. I've successfully performed other operations with it, i.e. getting a folder and getting messages, but am unable to send an email.
I'm using a MailHelper class provided in a Microsoft sample. This is the method:
internal async Task<String> ComposeAndSendMailAsync(string subject,
string bodyContent,
string recipients)
{
// The identifier of the composed and sent message.
string newMessageId = string.Empty;
// Prepare the recipient list
var toRecipients = new List<Recipient>();
string[] splitter = { ";" };
var splitRecipientsString = recipients.Split(splitter, StringSplitOptions.RemoveEmptyEntries);
foreach (string recipient in splitRecipientsString)
{
toRecipients.Add(new Recipient
{
EmailAddress = new EmailAddress
{
Address = recipient.Trim(),
Name = recipient.Trim(),
},
});
}
// Prepare the draft message.
var draft = new Message
{
Subject = subject,
Body = new ItemBody
{
ContentType = BodyType.HTML,
Content = bodyContent
},
ToRecipients = toRecipients
};
try
{
// Make sure we have a reference to the Outlook Services client.
var outlookClient = await AuthenticationHelper.GetOutlookClientAsync("Mail");
//Send the mail.
await outlookClient.Me.SendMailAsync(draft, true);
return draft.Id;
}
//Catch any exceptions related to invalid OData.
catch (Microsoft.OData.Core.ODataException ode)
{
throw new Exception("We could not send the message: " + ode.Message);
}
catch (Exception e)
{
throw new Exception("We could not send the message: " + e.Message);
}
}
My arguments are not null and seem to be correct. The error I'm getting is: "Cannot read the request body.".
I've made sure my application is registered with the right permissions so I'm at a loss. Does anyone know what's going on with my code?
Try capturing a Fiddler trace of the request and check the Content-Type header.
