I have a need to find a particular email on a Google IMAP server and then save the attachments from the email. I think I have it all figured out except for the part of determining what the file name is of the attachment.
Below is my code so far, I am hoping that someone can point me in the right direction to determine the file name.
I have Googled and SO'd but have not been able to find something using the attachment approach.
internal class MailKitHelper
{
private void SaveAttachementsForMessage(string aMessageId)
{
ImapClient imapClient = new ImapClient();
imapClient.Connect("imap.google.com", 993, SecureSocketOptions.Auto);
imapClient.Authenticate("xxxx", "xxxx");
HeaderSearchQuery searchCondition = SearchQuery.HeaderContains("Message-Id", aMessageId);
imapClient.Inbox.Open(FolderAccess.ReadOnly);
IList<UniqueId> ids = imapClient.Inbox.Search(searchCondition);
foreach (UniqueId uniqueId in ids)
{
MimeMessage message = imapClient.Inbox.GetMessage(uniqueId);
foreach (MimeEntity attachment in message.Attachments)
{
attachment.WriteTo("WhatIsTheFileName"); //How do I determine the file name
}
}
}
}
And the winner is.....
attachment.ContentDisposition.FileName

I'm using GemBox.Email and I'm retrieving unread emails from my inbox like this:
using (var imap = new ImapClient("imap.gmail.com"))
{
imap.Connect();
imap.Authenticate("username", "password");
imap.SelectInbox();
IEnumerable<string> unreadUids = imap.ListMessages()
.Where(info => !info.Flags.Contains(ImapMessageFlags.Seen))
.Select(info => info.Uid);
foreach (string uid in unreadUids)
{
MailMessage unreadEmail = imap.GetMessage(uid);
unreadEmail.Save(uid + ".eml");
}
}
The code is from the Receive example, but the problem is that after retrieving them they end up being marked as read in my inbox.
How can I prevent this from happening?
I want to download them with ImapClient and leave them as unread on email server.
EDIT (2021-01-19):
Please try again with the latest version from the BugFixes page or from NuGet.
The latest version provides ImapClient.PeekMessage methods which you can use like this:
using (var imap = new ImapClient("imap.gmail.com"))
{
imap.Connect();
imap.Authenticate("username", "password");
imap.SelectInbox();
foreach (string uid in imap.SearchMessageUids("UNSEEN"))
{
MailMessage unreadEmail = imap.PeekMessage(uid);
unreadEmail.Save(uid + ".eml");
}
}
ORIGINAL:
When retrieving an email, most servers will mark it with the "SEEN" flag. If you want to leave an email as unread then you can just remove the flag.
Also, instead of using ImapClient.ListMessages you could use ImapClient.SearchMessageUids to get IDs of unread emails.
So, try the following:
using (var imap = new ImapClient("imap.gmail.com"))
{
imap.Connect();
imap.Authenticate("username", "password");
imap.SelectInbox();
// Get IDs of unread emails.
IEnumerable<string> unreadUids = imap.SearchMessageUids("UNSEEN");
foreach (string uid in unreadUids)
{
MailMessage unreadEmail = imap.GetMessage(uid);
unreadEmail.Save(uid + ".eml");
// Remove "SEEN" flag from read email.
imap.RemoveMessageFlags(uid, ImapMessageFlags.Seen);
}
}
I just started using the open-source library called IMAPX to interact with my IMAP mailbox. I am following this article on CodeProject. I can login properly and retrieve the email folders. But the problem is, the article seems to be incomplete which is leaving me in the middle of the road. Firstly the Retrieving Email Folder's part didn't work. I had to do a workaround.Now, I am trying to download the emails of a folder.The article, regarding this issue, has only a few line of code:
private void foldersList_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
var item = foldersList.SelectedItem as EmailFolder;
if(item != null)
{
// Load the folder for its messages.
loadFolder(item.Title);
}
}
private void loadFolder(string name)
{
ContentFrame.Content = new FolderMessagesPage(name);
}
The article doesn't explain anything about FolderMessagesPage . So, I made a test page named FolderMessagesPage. I literally have no idea what to put in that page. Can anybody please guide me?
Unfortunately now I'm having some problems in accessing the article on Code Project, but if you need to retrieve the emails, you can start with the following sample code which retrieves the emails from the Inbox folder. I think that might work for you as well.
private static readonly ImapClient _client = new ImapX.ImapClient(ServerImapName, ImapPort, ImapProtocol, false);
if (!_client.Connect())
{
throw new Exception("Error on conncting to the Email server.");
}
if (!_client.Login(User, Password))
{
throw new Exception("Impossible to login to the Email server.");
}
public static List<string> GetInboxEmails()
{
var lstInEmails = new List<string>();
// select the inbox folder
Folder inbox = _client.Folders.Inbox;
if (inbox.Exists > 0)
{
var arrMsg = inbox.Search("ALL", ImapX.Enums.MessageFetchMode.Full);
foreach (var msg in arrMsg)
{
var subject = msg.Subject;
var mailBody = msg.Body.HasHtml ? msg.Body.Html : msg.Body.Text;
lstInEmails.Add(string.Concat(subject, " - ", mailBody );
}
}
return lstInEmails;
}
Hope it helps.
Good bytes.
I've been fighting this problem for some time now, and have failed to find an answer online that works. I am using the Exchange EWS API to do some email processing. One of the things I need to process is an EmailMessage that has attachments on it. One of those attachments happens to be another EmailMessage. I will refer to this as the attached EmailMessage.
I want to convert this EmailMessage to a byte[], however every time I try, I get an Exception. Below is my code:
if (((ItemAttachment)attachment).Item is EmailMessage)
{
EmailMessage msg = ((ItemAttachment)attachment).Item as EmailMessage;
msg.Load(new PropertySet(ItemSchema.MimeContent));
byte[] content = msg.MimeContent.Content;
}
The problem is no matter what I try to load, I get an exception thrown saying
An exception of type 'System.InvalidOperationException' occurred in Microsoft.Exchange.WebServices.dll but was not handled in user code
Additional information: This operation isn't supported on attachments.
If I don't call msg.Load(), I get a different error saying I need to load the content.
I don't understand this. If I do the same operation on an EmailMessage that was not attached to anything, it works just fine. Why does it matter that the EmailMessage was an attachment at one point in time? How can I get the EWS/.NET/Whatever is throwing the Exception to treat the attached EmailMessage as an EmailMessage and not an ItemAttachment?
You need to use the GetAttachments operations on Each on the Embedded Attachments with a propertyset that includes the MimeContent. eg something like (this can made a lot more effienct by grouping the GetAttachment requests if your processing multiple message etc).
PropertySet psPropSet = new PropertySet(BasePropertySet.FirstClassProperties);
psPropSet.Add(ItemSchema.MimeContent);
foreach (Attachment attachment in CurrentMessage.Attachments)
{
if (attachment is ItemAttachment)
{
attachment.Load();
if (((ItemAttachment)attachment).Item is EmailMessage)
{
EmailMessage ebMessage = ((ItemAttachment)attachment).Item as EmailMessage;
foreach (Attachment ebAttachment in ebMessage.Attachments)
{
if (ebAttachment is ItemAttachment)
{
Attachment[] LoadAttachments = new Attachment[1];
LoadAttachments[0] = ebAttachment;
ServiceResponseCollection<GetAttachmentResponse> getAttachmentresps = service.GetAttachments(LoadAttachments, BodyType.HTML, psPropSet);
foreach (GetAttachmentResponse grResp in getAttachmentresps)
{
EmailMessage msg = ((ItemAttachment)grResp.Attachment).Item as EmailMessage;
msg.Load(new PropertySet(ItemSchema.MimeContent));
byte[] content = msg.MimeContent.Content;
}
}
}
}
}
}
You have to load the attachment with the flag to load MimeContent:
{
if (attachment is ItemAttachment ia)
{
ia.Load(ItemSchema.MimeContent);
}
}
I'm reading emails using Imap. My code, which is working, is as follows:
Client.ConnectSsl(mailServer, port);
Mailbox mails = Client.SelectMailbox("inbox");
MessageCollection messages = mails.SearchParse("UNSEEN");
return messages;
But I want to get one email at a time instead of getting all the messages as a MessageCollection. I don't want to loop through MessageCollection either. Is there any method which returns only one message?
For example :
Message email = mails.Search("UNSEEN");
Thank you.
You can Find the below solution
Imap4Client imap = new Imap4Client();
imap.ConnectSsl("imap.gmail.com", 993);
imap.Login("abc#gmail.com", "thatsmypassword");
imap.Command("capability");
Mailbox inbox = imap.SelectMailbox("inbox");
int[] ids = inbox.Search("UNSEEN");
if (ids.Length > 0)
{
Message msg_first = inbox.Fetch.MessageObject(ids[0]);
}
Thanks,

Question
How would I look at the attachment properties using EWS (Exchange 2013, C#) and retrieve the original sender's email address? Not the email address of the current sender, but the sender of the email that is attached to this email.
What I Did
Lots of googling has shown me only how to retrieve the sender of the current email and not the attachement. I do this by
//get sender of email to TR
EmailMessage mes = (EmailMessage)item;
String sender = mes.Sender.Address;
Request
Thoughts? Links? Sample code? I am looking for anything right now that I can use to help me load up the attachment and pull the sender email address. Thanks!
You want to fetch details on attached emails right?
Try This Code Snippet? Assuming _ewsService is a correctly bound service client.
var results = _ewsService.FindItems(WellKnownFolderName.Inbox, new ItemView(100)); //fetch 100 random emails from inbox
foreach (var entry in results.Items)
{
if (entry is EmailMessage)
{
var temp = EmailMessage.Bind(_service, entry.Id);
if (entry.HasAttachments)
{
temp.Load(new PropertySet(EmailMessageSchema.Attachments));
foreach (var singleItem in temp.Attachments)
{
if (singleItem is ItemAttachment)
{
var attachedMail = singleItem as ItemAttachment;
attachedMail.Load();
Console.WriteLine(attachedMail.Item is EmailMessage);
var workingMessage = attachedMail.Item as EmailMessage; //this should give you from, subject, body etc etc.
}
}
}
}
}
