phplist

PHPlist using phpmailer, by default sets to send email with Content-Transfer-Encoding set to 8-bit. However, mail transport standards forbid lines longer than 998 characters and has to handle such non-compliant lines by breaking/folding them, or the next hop MTA (Mail Transfer Agent) might reject the message or truncate the lines.

The fix for the problem is to use "base64" or "quoted-printable" encoding, which will fold the lines in a way that can be undone by the recipient MUA (Mail User Agent).

If using phplist with phpmailer, the file to edit would be "admin/phpmailer/class.phpmailer.php", as below:

PHPList comes with FCKeditor as the gui default editor. However, by default it is setup so that the spellcheck is only available to IE users. To enable for other browsers such as Firefox, follow the below directions:

1. Edit admin/fckphplist.php:
   
2. Replace all instances of:
   
   FCKConfig.SpellChecker      = 'ieSpell' ;

   with:

   FCKConfig.SpellChecker      = 'SpellerPages' ;

3. Edit admin/.htaccess and add "spellchecker.php" to the list of files to allow access to.
   
4. If this is a linux box, then make sure aspell is installed. Edit "admin/FCKeditor/editor/dialog/fck_spellerpages/spellerpages/server-scripts/spellchecker.php" and update the aspell program path:
   $aspell_prog    = '/usr/bin/aspell';

That should do it.
