Hugh Leyton. Recommended Answer. Hi Raymond. Confusing isn't it. How do you think those messages got "Archived"?
Despite the name, there is no Archive folder. There are no Folders in G-mail, even more confusing. All G-mail does is attach labels to messages.
It's the first time I've used MailKit and I'm a bit stumped around the best way to do this. Essentially, I want to write an async method hosted in a class library that downloads emails based on a simple header text search and invokes a callback each time so I can update the GUI.
My attempt to do this is given in the following method.
However, I feel there is a lot of code for what I want to do - do I really need to call so many async methods to get the messages, is it essential to have everything inside the using statement, or are there any obvious objects that I can cache.
Is there a way that I can rewrite this method so I do not have to include the callBack action? Also, I'm a bit unsure about the types of exceptions I can sensibly expect to handle, timeouts etc It's hard to say how to write the ideal method for your use-case because you don't specify some of the details that would be necessary to know, such as:. I changed your code to put the entire block of logic into a single task which will all run on the same thread rather than your previous block which would effectively just run synchronously anyway since it didn't actually parallelize anything it can't, really, since you can't search a folder until you've opened the folder - which you can't do until you've authenticated - which you can't do until you've connected, etc.
As far replacing your GetMessageAsync logic goes, since the ImapClient can only process a single command at a time anyway, it doesn't make sense to spawn potentially thousands of command tasks asynchronously so that they can all just hurry up and wait for the previously queued tasks. Better to just write a synchronous loop in this scenario.
Update This will no longer be the case in MailKit 2. Run which means that they will no longer spawn threads.

NET Core 3. MailKit is an Open Source cross-platform. NET mail-client library that is based on MimeKit. It is optimized for mobile devices and support for all modern protocols. I was looking to build an send email functionality as a Service using.
I have used my own Gmail modified below for sending an email and testing purpose which worked very well after some initial travail. A message structure consists of header fields and a body. The body of the message can be plain text or tree of MIME entities. For the Gmail SMTP server, the above code worked perfectly for me except I had to update a few security settings as mentioned below.
Gmail by default prevents you to access your e-mail account from external applications. But you can update your security settings to accept the login from the application. Such errors are more due to policy configured on the SMTP email server.
Working with messages
Make sure you are following proper settings and policies required for a secure connection to connect to the SMTP server. Apart from sending email MaiKit library also provides support for retrieving messages from pop3 servers.
Today in this article we learned how to send an email message using MailKit a. NET open-source library. Please share this article with your friends and Subscribe to the blog to get a notification on freshly published best practices of software development.A common misunderstanding about email is that there is a well-defined message body and then a list of attachments.
This is not really the case. The reality is that MIME is a tree structure of content, much like a file system. The Content-Disposition header is meant to provide hints to the receiving client as to which parts are meant to be displayed as part of the message body and which are meant to be interpreted as attachments. The Content-Disposition header will generally have one of two values: inline or attachment.
The meaning of these values should be fairly obvious. If the value is attachmentthen the content of said MIME part is meant to be presented as a file attachment separate from the core message. However, if the value is inlinethen the content of that MIME part is meant to be displayed inline within the mail client's rendering of the core message body.
If the Content-Disposition header does not exist, then it should be treated as if the value were inline. Technically, every part that lacks a Content-Disposition header or that is marked as inlinethen, is part of the core message body.
The reason for sending the message text in both formats is that not all mail clients are capable of displaying HTML. Since alternative views are listed in order of least faithful to most faithful with what the sender saw in his or her WYSIWYG editor, the receiving client should walk over the list of alternative views starting at the end and working backwards until it finds a part that it is capable of displaying. Generally, it will either be a TextPart or a Multipart. There are 3 ways of iterating over the tree structure of a message using MimeKit.
The first way is to recursively traverse the MIME structure like this:. A second way, which is a bit cleaner and doesn't require recursive methods, is to use a MimeIterator :. And finally, for those that prefer to use the visitor patternMimeKit includes the MimeVisitor class for visiting each node in the MIME tree structure.
These are TextBody and HtmlBodyrespectively. This property is really only a convenience property and is not a really good substitute for traversing the MIME structure yourself so that you may properly interpret related content. For this reason, MimeKit provides the BodyParts and Attachments properties which flatten out the hierarchy and allow you to iterate over all of the body parts or attachments in depth-first order.
At some point, you're going to want to extract the decoded content of a MimePart such as an image and save it to disk or feed it to a UI control to display it.
Once you've found the MimePart object that you'd like to extract the content of, here's how you can save the decoded content to a file:. You can also get access to the original raw content by "opening" the Content. This might be useful if you want to pass the content off to a UI control that can do its own loading from a stream.
There are a number of useful filters that can be applied to a FilteredStreamso if you find this type of interface appealing, I would suggest taking a look at the available filters in the MimeKit.
Filters namespace or even write your own!

We implemented a small email client to retrieve emails from a gmail account for an end to end test spec using.
When running the tests through the test explorer on Visual Studio the test works correctly and emails are retrieved from the gmail account. The issue only happens when running the tests outside of visual studio through CLI. The below exception is thrown when opening the email inbox folder. We installed the MimeKit dependency as a direct dependency of our project which still did not resolve the issue. Exception: Step 5: System. ParserOptions' threw an exception.
CharsetUtils' threw an exception. The system cannot find the file specified. Log File: imap. Adding an extra point with nismolo: One thing that I've noticed it is failing to load System. But when I've checked the nuget repo the version 4. Just because you don't see a nuget version on nuget. MailKit also does not depend on System. Just went through my releases of MailKit and it has depended on System. CodePages 4. Maybe you just need to update? We did further investigation and it seems its happening only when directly using the dotnet xunit command to run tests.
It works just fine when using dotnet test command. Skip to content. Dismiss Join GitHub today GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Sign up. New issue. Jump to bottom. Labels question.

My first step and my question are : How can I retrieve emails from an exchange mailbox using C? In all my research, I am finding how to send emails but not retrieve them. I don't want to use third party APIs and would like to keep it as simple as possible Can some one please point me in the right direction? Thanks in advance Exchange mailbox. GetDefaultFolder Outlook. MailItem mail in inbox. That's a good piece of code. I guess this library connects Outlook and uses one of my saved profiles to connect the exchange server.
I read somewhere that "If you need to get data from another user's Exchange mailbox, you can use CDO not officially supported in. If so, you may want to try using the respective protocol. It will probably be cleaner than using OL.
