Is the log line

rcpt to:thomas.bindel@???
450 4.2.0 <thomas.bindel@???>: Recipient address rejected:
Greylisted, see http://postgrey.schweikert.ch/help/htw-dresden.de.html

not prove enough that the callout has got a 450 return code?

Yes. It is absolutly repeatable. I also checked all four receiving
mailservers they are all graylisted.

Tried to capture, but the connection is TLS, so no useful information
could be obtained.

220 rmx5.rz.htw-dresden.de ESMTP Postfix (Debian/GNU)

EHLO mail.inqbus.de

250-rmx5.rz.htw-dresden.de

250-PIPELINING

250-SIZE 30720000

250-VRFY

250-ETRN

250-STARTTLS

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

STARTTLS

220 2.0.0 Ready to start TLS


Which debug switch do I need to get useful information on the return
codes. Has exim to be run in the foreground?

Cheers

Volker
