Features

Information on what features each of the clients support.

General features

For all of these clients, the concept of "HTML support" does not mean that they can process the full range of HTML that a web browser can handle. Almost all email readers limit HTML features, either for security reasons, or because of the nature of the interface. CSS and JavaScript can be especially problematic.

  3. ↑ First release 6.0 (September 2003), enhancements introduced in release 7.0 (August 2005)
  4. ↑ Although Thunderbird supports UTF-8, its handling of line wraps causes problems with long lines of text that don't contain spaces, which essentially makes it unusable for certain languages (e.g. Chinese, Japanese, Korean)
  5. ↑ Mozilla Thunderbird adds this feature in Thunderbird 1.5.0.4
  6. 1 2 3 Using PGP in Thunderbird before version 78 requires Enigmail.
  7. 1 2 3 PGP/GPG and S/MIME support require a free (included) plugin.
  8. ↑ Using PGP in Outlook Express requires a plugin.
  9. ↑ Outlook Express does not display PGP/MIME signed messages.
  10. ↑ Sylpheed has some limited ability to show HTML email. It can show the plain text that's left after stripping away all the HTML tags. Sylpheed has no ability to compose HTML.
  11. ↑ The Bat is not able to display inline images.
  12. 1 2 3 The Bat! supports two modes of S/MIME: Internal Implementation and via Microsoft CryptoAPI. [Note 13] CRLs and OCSP are only supported in the latter mode. Internal implementation only supports Aladdin eToken Pro or Rainbow iKey1000 [Note 14] tokens and can import certificates (from PKCS#12/PFX format) which were created outside The Bat!. CryptoAPI supports any kind of tokens and smart cards which have a corresponding Cryptographic Service Provider installed.

  1. 1 2 It's a frequent problem for people dealing with Cyrillic/Russian in email messages that the message is not encoded in the encoding declared in its headers and thus can't be read. With such a message (with a wrong declaration of the encoding), it well might be the case that it passed through several incorrect recoding stages while it was being sent and delivered; thus it's not possible to correctly render it and read it if one uses the common type of the interface for choosing the encoding (such as the menu in Mozilla Firefox). An example of such a complex case of a wrongly declared encoding: a message was entered through a webform in the windows-1251 encoding, but the web interface incorrectly assumed that it was in latin-1; based on this assumption, it performed the recoding from latin-1 to utf-8. The result of this operation cannot be correctly decoded through the common encoding-selection interface; it can only be decoded through a two-stage recoding: first from utf-8 to latin-1, then from windows-1251 to utf-8 (assuming that one works in a Unicode environment). After it is decoded, it is desirable to store it in the recoded form instead of the original, in order to be able to read it easily afterwards, and to quote it for replies.
  2. ↑ i.Scribe / InScribe supports full integration with GNU Aspell, which is its requirement for spell checking.
  3. ↑ i.Scribe / InScribe requires libjpeg.
  4. ↑ i.Scribe / InScribe requires libpng.
  5. ↑ Entourage can link a message to a note.
  6. ↑ Configurable to start replies at top or bottom, with separate configuration of signature position
  7. ↑ Thunderbird requires SL8TR extension.
  8. ↑ Starts replies with cursor at top, but is configurable regarding whether to include a blank space at the top for replies or not; some interleaved-posting users prefer starting the cursor at the top so they can trim the quotes
  9. ↑ The recoding engine and interface extensions that would solve the described recoding problems have been developed as a patch for Pine; it is to be found in the package pine-4.58L-alt4.src.rpm Archived 2011-08-27 at the Wayback Machine (ftp) for ALTLinux (under the name pine-4.58L-alt2-0.4.1.diff ). Its essential feature is to enable to forcibly recode messages, save them in the recoded form, and quote in replies.
  10. ↑ Pine supports full integration with GNU Aspell or other external speller, which is its requirement for spell checking.

Multipurpose Internet Mail Extensions (MIME) is a standard that extends the format of email messages to support text in character sets other than ASCII, as well as attachments of audio, video, images, and application programs. Message bodies may consist of multiple parts, and header information may be specified in non-ASCII character sets. Email messages with MIME formatting are typically transmitted with standard protocols, such as the Simple Mail Transfer Protocol (SMTP), the Post Office Protocol (POP), and the Internet Message Access Protocol (IMAP).

In computing, the Post Office Protocol (POP) is an application-layer Internet standard protocol used by e-mail clients to retrieve e-mail from a mail server. Today, POP version 3 (POP3) is the most commonly used version. Together with IMAP, it is one of the most common protocols for email retrieval.

S/MIME is a standard for public-key encryption and signing of MIME data. S/MIME is on an IETF standards track and defined in a number of documents, most importantly RFC 8551. It was originally developed by RSA Data Security, and the original specification used the IETF MIME specification with the de facto industry standard PKCS #7 secure message format. Change control to S/MIME has since been vested in the IETF, and the specification is now layered on Cryptographic Message Syntax (CMS), an IETF specification that is identical in most respects with PKCS #7. S/MIME functionality is built into the majority of modern email software and interoperates between them. Since it is built on CMS, MIME can also hold an advanced digital signature.
