You might try not advertising STARTTLS on connections from 217.72.192.242
See the tls_advertise_hosts option
If you already don't advertise STARTTLS, this is not the solution.

Many of the options are not stated explicitly in the configuration file.
Execute
exim -bP smtp_receive_timeout
You'll likely find out that the timeout is 5 minutes. Should be long
enough.

They should either be retried later (and eventually bounced) or bounced. It
depends upon how
fmmailgate04.web.de
treats whatever error it is seeing when connected to your server (as
permanent or temporary). The best way to find out is probably to
experiment.
