I'll be going with a direct DB edit which I'm documenting here for the next
person. Since I just want to suppress the file and do not want to hide the
fact that it existed. Here is what I did, be very careful! If you don't
know SQL or you don't understand every step below then find someone else to
help you - this is the WRONG PATH for you:

1 Get the attachment id of the attachment to remove (as of RT 4.4.1  it's
the *second* number in the URL that displays the attachment).

2 Add a comment to the ticket indicating that you are deleting the
offending attachment for policy violation (or whatever you motive).

3 Run this command to improve your odds of not messing up and deleting the
wrong transaction:
> select id, Transactionid, MessageId, Subject, Filename, ContentType,
ContentEncoding, Headers, Creator, Created from Attachments where id=

4 If that looks right to you then run this SQL against A TEST COPY OF YOUR
DB to ensure you are killing the right attachment
> update Attachments set Content = NULL where id =

5 Go look at the ticket in RT and ensure that you did indeed eliminate the
offending attachment.

6 Repeat steps 3,4,5 in your production environment.

7 Do not call me if you shot yourself in the foot. No warranty expressed or
