Hi,
I've got a report from a user that tries to send an mail from GMX to my private mail account.
The mail-account is secured by DANE/TLSA and running on Postfix. "dane.sys4.de" does not report any issues, but GMX refuses to deliver mail with this message:
----------------------------schnipp---------------------------- This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
cas@strotmann.de: remote MX does not support STARTTLS ----------------------------schnipp----------------------------
Has anyone seen a similar issue? Any ideas how to troubleshoot?
Best regards
Carsten
