Available Platforms

Included with PowerTCP Mail for .NET

 

Features

Feature Overview
  • 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 (Office 365, 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)
SMTP, POP3, IMAP4 components interact with servers
  • Integrates .NET features, including generics, IPv6, dual-stack sockets and X509 certificates
  • Secure: Link-level encryption (SSL 2.0, SSL 3.0, PCT, TLS 1.0, 1.1, 1.2, 1.3) is controlled using simple session properties
  • Progress events report message upload/download activity
  • Log events report data for debugging and display purposes
  • Send any custom command using the exposed TCP connection
MailMessage class at the core of the system
  • Represents a decoded MIME, Secure MIME (S/MIME), or non-MIME (straight ASCII) Internet email message
  • Dynamic encoding occurs when the encoding stream is read from; dynamic decoding occurs when encoding stream is written to
  • Can be used independent of protocol components as a general-purpose MIME or S/MIME encoder/decoder
  • Rich object model represents each header, text, html, attachment, part, and resource element
  • Attachments are decoded and stored in temp files by default, but can optionally be stored in MemoryStreams if disk access is not desired
  • Fast on-the-fly message decoding eliminates intermediate files and delays by streaming encoded message data from the source server to the destination MailMessage
SMTP is for sending email
  • Authentication support: OAuth 2.0 (XOAUTH2), CRAM-MD5, GSSAPI and NTLM (with single-sign-on), LOGIN, PLAIN
  • Messages can be sent via relay servers, intermediate mail servers, or directly to recipients' domain mail servers
  • Send simple email with a single line of code, or build a complex MailMessage and send it
  • Delivery Status Notification (DSN) fully supported
  • Supports pipelining of commands without waiting for server acknowledgments
POP3 is for downloading email
  • Secure
    - Authentication support: OAuth 2.0 (XOAUTH2), CRAM-MD5, GSSAPI and NTLM (with single-sign-on), LOGIN, PLAIN, clear-text, APOP
    - Decrypt and/or verify signed S/MIME messages
  • Easy message management - default behavior populates message size and id without downloading message content
  • Dynamic message retrieval - populate selected messages with just the header, header plus a little content, or the entire message
IMAP4 downloads mail too, and adds remote mail management
  • Secure
    - Authentication support: OAuth 2.0 (XOAUTH2), CRAM-MD5, GSSAPI and NTLM (with single-sign-on), LOGIN, PLAIN, clear-text
    - Decrypt and/or verify signed S/MIME messages
  • IMAP4 commands synchronize the local object model with the server (change the local model and the server is changed)
  • ImapMessage class represents a message in a mailbox - use to change server-side message flags and get a single message
  • Mailbox class represents a server-side mailbox that contains messages - use to alter mailbox properties, enumerate messages, get messages in bulk and append new messages
  • MailboxCollection class represents child mailboxes - use to manage nested mailboxes
  • Update event informs client of dynamic updates to the selected mailbox
  • Retrieve an entire message, headers only, attachments only, or any part desired

 

Ease-of-Use and Efficiency

Ease-of-Use is an attribute of class design
  • Class properties are used for several purposes, making the object model more concise and easier to learn:
    • Default (uninitialized) values will work for most applications, so research may be avoided
    • Configuration properties control behavior (like SSL security), so users are usually spared low-level detail programming
    • Configuration properties are grouped in classes that can be easily serialized for later use
    • Some properties are high-level shortcuts. MailMessage.Html will search MailMessage.Parts to return text from the first "text/html" part found
  • Classes merge low-level detail (typically properties that can be read) with high-level methods (that use overloads to provide default parameters). This technique combines completeness with ease-of-use.
  • F1 help documentation is fully supported.
  • MessageEditor control (with source code) is provided to visualize and/or edit any MailMessage.
  • Reuse
    - Existing .NET Mail and Mime classes are reused (MailAddress, MailAddressCollection, ContentType, ContentDisposition, etc.), minimizing the product learning curve and enhancing stability.
    - Sample applications provide dialog boxes that can be quickly customized.
    - Class hierarchy is carefully designed to locate selected convenience properties and methods in base classes for re-use by derived classes.
System segmentation promotes efficiency
  • MailMessage (and other classes derived from Part) localize message creating, editing, and interpretation.
  • MailMessage.GetEncodingStream() returns a Stream that performs encoding and decoding.
    - Using Write(), the provided buffer is decoded and the MailMessage is incrementally populated.
    - Using Read(), the provided buffer is filled with the next encoded segment that can be streamed to the server.
    - Encoding/decoding is interleaved with socket operations, resulting in optimal performance.
  • Smtp, Pop, and Imap components are optimized for socket communications. Messages are transferred on demand. Worker thread efficiently sleeps while waiting for socket data.
