email notification error

yes, but I can't find anything. As far as I can see, they mostly are about the fact the mails just won't go out. My mails do go out when the checkout is completed, I just keep getting the error message on the screen.

On my localhost (no mail configured) I'm getting the error message twice, though I should be getting it only once, since drupal only tries to send one mail.
On the live site I get the message once and one mail is sent successfully.

So I gather that somehow an extra error message is created, but I have no idea what triggers it.
I can't deliver the site like this. It just won't do.

Turning off the error messages in the config error logging section doesn't help.

I saw something strange in the permissions section :
I seem to have to order permission series - see attachment.
Could this be a reason why I get the email error messages? How can I get rid of the second series?
Jus forget about that - saw that in a clean install of kickstart 1, this also figures like that, but I can't delete it in this post.

I also get the following error message in the dblog files :
Error sending e-mail (from cccc_at_belgacom.net to jdebeuckelaer_at_yahoo.com). this one is normal, since I'm on my localhost
Error sending e-mail (from cccc_at_belgacom.net to commerce-order:mail)

In the clean install the same standard rule is configured as in my site, but in the clean install it doesn't give any error messages for it.
Could it have something to do (again) with translations?
I'm really getting desperate - now that everything is working well, this just won't work.

As I said, my mails are being sent out properly by drupal. There's no problem with that.
I didn't mess with the email notification rule. I only translated the content of the email.
I did revert it to its original state, and that doesn't make a difference.
I did post this and another problem I had to your drupalcommerce site, but don't get any replies. And people who posted similar problems, don't get answers either.
The only reaction I get to my questions is you, because I turn on the status to "active".
I also checked on the multilingual posts and no answer there either.
So, you must understand that I'm getting frustrated.

this is my link at DC :

the other question I put, I solved myself :
http://www.drupalcommerce.org/questions/8087/shipping-and-billing-inform...

Just for your info : when I went to look for the links on DC just now, I'm getting a whole screen of the following error msgs on the pages.

Warning: include_once() [function.include-once]: Unable to allocate memory for pool. in drupal_settings_initialize() (line 712 of /mnt/www/html/dcorg/docroot/includes/bootstrap.inc).
Warning: require() [function.require]: Unable to allocate memory for pool. in require() (line 520 of /mnt/www/html/dcorg/docroot/sites/default/settings.php).

etc.

Hey Ryan
Just wanted you to know : I found the culprit! It was the bank transfer module that created a rule that also sends an email to commerce-order:mail. I disabled it and not everything works fine.
