Consulting and Custom Development

From email creation to complete mail systems, let our experienced staff help with your Mail project.
Here are some of the solutions we have delivered.

Manage email using standards-based protocols

  • Simple Mail Transfer Protocol (SMTP) and Post Office Protocol (POP3) components send and receive email, respectively
  • Internet Message Access Protocol (IMAP4) component manages email on IMAP4 servers (Gmail, Yahoo, Exchange, etc.)
  • Multipurpose Internet Mail Extensions (MIME) enable the encoding and decoding of non-ASCII data like international UNICODE text and binary data
  • Secure/Multipurpose Internet Mail Extensions (S/MIME) version 3.0, 3.1, 3.2 enable message signing (authentication) and encryption (privacy)
  • more ... 

Integrated security protects data at 3 levels

  • Level 1: comprehensive login options authenticate the client to the server (APOP, CRAM-MD5, LOGIN, PLAIN, GSSAPI, NTLM, XOAUTH2 (OAuth 2.0), clear-text, AUTO)
  • Level 2: SSL2, SSL3, PCT, TLS 1.0, 1.1, 1.2 implements end-to-end encryption between your application and the email server
  • Level 3: S/MIME encoding/decoding authenticates the integrity and author of the message and encrypts the content
  • Included X509 certificate management support is used to manage security at levels 2 and 3

Ease-of-Use, Efficiency, Stability

  • Create HTML mail (MHTML) from HTML documents with one line of code
  • MailMessage class provides a nested hierarchy of MIME entities (parts) you can easily manipulate:
    • Properties expose header labels and enumerate multipart content
    • Author email of any complexity
    • IsMime property to control the use of MIME encoding on a per message basis.
    • Included MessageEditor control (with source code) provides a message viewer/editor
  • MailMessage.GetEncodingStream() returns a Stream that decodes when Write() is called (the MailMessage is incrementally populated with decoded content) and encodes when Read() is called (the user's buffer is filled with the next segment of the encoded MailMessage)
  • Suitable for advanced WinForms applications as well as single-threaded services, console and web applications
  • Winform samples demonstrate robust multi-threading features and Task-based Asynchronous Pattern (TAP)
  • .NET-centric, reusing classes from System.Net.Mail and System.Net.Mime
  • more ...
