They certainly exist. I was sent a problem report last week which
allegedly contained our response to their mail offer. In this
particular situation, we emit a single long line, which exim
apparently breaks after the word "Please".
deny message = "This email scored $spam_score spam points \
${if >{$ACL_BLACKLIST}{0}{(+$ACL_BLACKLIST leak) }{}}\
and was rejected. Please contact \
[EMAIL PROTECTED] if this is a mistake.
The remote MTA told its user that we'd responded as follows:
X-Supplementary-Info: <cernmxlb.cern.ch #5.5.0 smtp;550-"This email
scored 0.0 spam points (+90 leak) and was rejected. Please>
Consequently the invitation to contact our postmaster for assistance
had been suppressed.

A certain dominant vendor does not read interworking specifications,
that's only too clear.
