MailKitSimplified

Sending and receiving emails sounds simple, after all, electronic mail existed decades before the Internet. If you're looking for an all-in-one .NET solution for email, you'll quickly discover MailKit is recommended by even the likes of Microsoft due to how it implements the RFC standard. Unfortunately the downside of doing it all is that MailKit can be difficult to set up and use, especially the first time you go to try something like working with attachments or writing a reply. The aim of this package is to make sending and receiving emails as simple as possible!

SMTP with MailKitSimplified.Sender

Sending an email with MailKitSimplified.Sender is as easy as:

using var smtpSender = SmtpSender.Create("localhost");
await smtpSender.WriteEmail.To("test@localhost").SendAsync();

IMAP with MailKitSimplified.Receiver

Receiving emails with MailKitSimplified.Receiver is as easy as:

using var imapReceiver = ImapReceiver.Create("localhost");
var mimeMessages = await imapReceiver.ReadMail.GetMimeMessagesAsync();

Example Usage

The examples above will actually work with no other setup if you use something like smtp4dev, but below are some more realistic examples.

Sending Mail

using var smtpSender = SmtpSender.Create("mail.example.com:587")
    .SetCredential("U5ern@m3", "P455w0rd")
    .SetProtocolLog("Logs/SmtpClient.txt");
await smtpSender.WriteEmail
    .From("[email protected]")
    .To("[email protected]")
    .Bcc("[email protected]")
    .Subject("Hello World")
    .BodyHtml("<p>Hi</p>")
    .Attach("appsettings.json")
    .TryAttach(@"Logs\ImapClient.txt")
    .SendAsync();

See the MailKitSimplified.Sender wiki for more information.

Receiving Mail

using var imapReceiver = ImapReceiver.Create("imap.example.com:993")
    .SetCredential("U5ern@m3", "P455w0rd")
    .SetProtocolLog("Logs/ImapClient.txt");
var mimeMessages = await imapReceiver.ReadFrom("INBOX")
    .Skip(0).Take(10).GetMimeMessagesAsync();

To just download the email parts you want to use:

var messageSummaries = await imapReceiver.ReadFrom("INBOX/Subfolder")
    .GetMessageSummariesAsync(MessageSummaryItems.UniqueId);

See the MailKitSimplified.Receiver wiki for more information.
