as my job is mail-admin and software-developer including development
of admin-backends for mailsystems and bounce-management systems i am
able to read a maillog line

554 "in reply to end of DATA command" is NOT a valid reason to disable
a account, this would only be valid "in reply to RCPT TO command" which
indicated that the RCPT address does not accept email

(host barracuda.thelounge.net[91.118.73.20] said: 554 rejected due to
spam content (in reply to end of DATA command))

and as long as i have no information of the specific rejected messages
in the suspend-notify it is impossible for me to observe the reason why
a message was blocked and mark it as ham to train the filter

Unless covered by a more precise response code, response code 554 is
   to be used to reject a MAIL FROM, RCPT TO, or DATA command that
   contains something improper.  Enhanced status code 5.6.0 is to be
   used if no other code is more specific.
