Plain exiscan-acl does not patch deliver.c (only the BMI code does, but
I guess this is not involved here).

To avoid confusion: The remote side is using exiscan, and is packing the
SA report into the 550 response. SA reports can be huge, up to multiple
kilobytes, so I would call this insane. Still there seems to be a bug,
but I guess it's not exiscan-related (since my code does not deal with
remote responses).

Philip, I could check for this bug since I'm currently testing anyway.
