"No SMTP response to data-dot"-message and delivered the message like 10 times

Fri Apr 7 14:27:50 CEST 2017

I don't think so. I've send a lot of e-mails just before that e-mail and 
a lot afterwards from exactly the same ip address, also using 
thunderbird...
but the problem only appeared with that single message.
And as I said, the really annoying part was, that the message got 
delivered more than 10 times (each time I deleted it, it reappeared a 
few hours later again, first I thought I'm becoming crazy ;-)))
