View source for CalMail language settings

=== A potential problem ===

The default web browser client for ''CalMail'' is ''SquirrelMail''. The default ''language'' in ''SquirrelMail'' is ''English''. With that default setting the text messages you compose will have

 Content-Type: text/plain;charset=iso-8859-1

in their header irrespective of whether your message or a portion of it may contain higher Unicode glyphs (e.g., Central European, Cyrillic, Greek, Hebrew,...). This will cause a number of mail clients to display your message incorrectly, including ''SquirrelMail'' itself which will display your message in the ''Sent'' folder filled with garbage HTML macros for each higher Unicode glyph you entered.

=== Solution ===

Change your language in ''Options > Language'' to ''any'' language but ''English'' (e.g., to ''British'', ''Polish'', ''Russian'',...). Now all your text messages will be sent with the directive

 Content-Type: text/plain;charset=utf-8

which ensures that basically any mail client will display the text of your message correctly, including ''CalMail'''s own ''SquirrelMail'' that will now correctly display your message in the ''Sent'' folder.

Changing the default language ''English'' to another language in ''Options'' has also the visible effect of several buttons now carrying labels in that language; the same with some messages. If you prefer to keep those labels and messages in English switch the language option from  ''English'' to ''British''.


An alternative is to use ''RoundCube'' mail client (the link provided on the ''CalMail'' web page). ''RoundCube'' sends all your plain text messages with

 Content-Type: text/plain;charset=utf-8

whether your selected language is ''English'' (the default), or any other one.

Note that in the ''RoundCube'' the default mode when you compose a message is ''HTML mark-up'', but you can always switch to the ''plain text mode'' by pressing the corresponding button in the ''Compose'' window.
