Features[edit]
Information on what features each of the clients support.
General features[edit]
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.

- ^Outlook Express does not display PGP/MIME signed messages.
- ^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.
- ^The Bat is not able to display inline images.
- ^ abcThe Bat! supports two modes of S/MIME: Internal Implementation and via Microsoft Crypto API.[65] CRLs and OCSP are only supported in the latter mode. Internal implementation only supports Aladdin eToken Pro or Rainbow iKey1000[66] 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.

- ^ abIt'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.
- ^i.Scribe / InScribe supports full integration with GNU Aspell, which is its requirement for spell checking.
- ^i.Scribe / InScribe requires libjpeg.
- ^i.Scribe / InScribe requires libpng.
- ^Entourage can link a message to a note.
- ^Configurable to start replies at top or bottom, with separate configuration of signature position
- ^Thunderbird requires SL8TR extension.
- ^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
- ^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(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. - ^Pine supports full integration with GNU Aspell or other external speller, which is its requirement for spell checking.
