Hi Falko, thanks for your reply!
If i add a e-mail routing for aon.at, all mails fetched with getmail will also be forwarded, so i get a loop (aon pop account > getmail > local smtp > aon smarthost smtp > aon popaccount. the aon smtp server detects the loop and dropped the mail
And Thunderbird keeps display the message, if i try to send to an aon.at address.
