@grepular Just discovered emailprivacytester.com and love it! However, it seems that your own server (pierre) triggers two of the traps.
Oh. #502
Edit: Works again.
@RaphaelWimmer I'm sure. The problem is I just migrated it without caring about downtime, and there was a 24h TTL on the DNS records, so the new server is currently trying to post DNS lookup tests to the old server. Try again tomorrow.
If I was paid to run this service I would have been more careful with the migration ;)
@grepular Thanks a lot for this service and the responses!
I'll try tomorrow. :)
