Hi Jean Charles,

Thanks for the quick response, but it is not having an effect.

I tried also with
#$mime_drivers['imp']['text/plain']['limit_inline_size'] in case you
had made an error with the mime type, but that does not change the
outcome.

I also tried text/enriched and text/html - also with no success.

27 $mime_drivers['imp']['text/plain']['limit_inline_size'] = 4194304;
 28 $mime_drivers['imp']['text/html']['limit_inline_size'] = 4194304;
 29 $mime_drivers['imp']['text/enriched']['limit_inline_size'] = 4194304;
 30 $mime_drivers['imp']['image/jpeg']['limit_inline_size'] = 4194304;

Interestingly, a blank mime_drivers.local.php with incorrect ownership
(root:root, instead of www-data:www-data) does cause the whole mail to
load - but with no line breaks!  In any email, whether plain-text or
html.
