Actually, it seems as if even nbSMTP is resending emails:
Code:
################################################## ##################
# THIS IS A WARNING ONLY. YOU DO NOT NEED TO RESEND YOUR MESSAGE. #
################################################## ##################
Your message could not be delivered for 24 hour(s).
It will be retried until it is 4 day(s) old.
For further assistance, please see (german lanuage only):

The Postfix program
<Kxxxx@Exxxxx.de>: host xxxx.Exxxxx.de[xx.xxx.xxx.xx] said: xxx-xxx.xxx.xx.xx
is not yet authorized to deliver mail from 451 <xxxxxxx@xxxxxxx.xxxx> to
<xxxxx@xxxxxx.de>. Please try later. (in reply to RCPT TO command)
Looks like this game is having a good hosting frequency so far.
