sorry to bother you in pd-dev with this, but i cant send any messages to pd-list :/

i can login with huolong@arcor.de and my pass to the config site of pd-list, but when i try to send emails, i get this:

"pd-list@iem.at: host dns.iem.at[193.170.191.180] said: 451-151.189.21.42 is not yet authorized to deliver mail from huolong@arcor.de 451 to pd-list@iem.at. Please try later. (in reply to RCPT TO command)"

(in attachment is the whole mail)

this happened to my last ~3mails, but it used to work, like half year a go, or so...

i could register new with my andre@osku.de mail (that i use for pd-dev) but i just wanted to know why i cant post...

or am i banned ? ^^*
