Package: squirrelmail Version: 1.4.9a-2 Quite simply, squirrelmail uses a default text/html for PDF attachments, which renders them unreadable to some (many?) less computer literate recipients.
The trivial addition of:
'pdf' => 'application/pdf',
to $FileExtensionToMimeType at the top of functions/attachment_common.php
resolves this issue.
