As per an email conversation i recently had (with myself so far) on the mantis mailing list the sort order of notes in emails is not respected - unlike the NUMBER of notes attached.

See my email:

Hi, I am playing with the number of
bug notes emailed and the order in which they appear. I have
found the following

$g_default_bugnote_order
= 'DESC';
$g_default_email_bugnote_limit
= 2;

BUT the sort order does NOT apply to emails. I can not seem
to change the order in which bugs appear in emails. Is this
a bug? I really want to limit the number of notes emailed
and have the new ones at the top.

Secondly these changes - although default no not seem to
override an existing users settings even if that user has
never changed them. Is only applied to new users/users that
reset prefs. Is this desirable?

Hi all i am now quite confident this is a bug. i have been playing about with the emai_API.php and notice this call

$t_user_bugnote_order = user_pref_get_pref ( $p_user_id, 'bugnote_order' );

in function email_build_visible_bug_data

The value inserted into t_user_bugnote_order MUST be incorrect as when i hard code values of ASC or DESC as follows

$t_bug_data['bugnotes'] = bugnote_get_all_visible_bugnotes( $p_bug_id, $t_user_access_level, 'DESC', $t_user_bugnote_limit );

I get the desired effect - i.e. the bug note ordering in emails actually changes.

Unfortunately I think I have hit my limit of testing as I dont know how to get debug output of out mantis. I am going to raise this as an issue.
