Yeah, I ended up doing something like that.
If I have any instances of the attachment type that needs rewriting and I have
more than one recipient, then I set a flag that I need to "fork" this message
to individual recipients, and I leave the attachment untouched (I'll get it on
the 2nd pass).
If, conversely, I only have a single recipient, then I do the rewriting in
filter().
If I did see the flag, then in filter_end() I call stream_by_recipient().
BTW, the return value of stream_by_recipient() isn't documented.
Also, if I'm running on a Postfix install (and I am), do I need to do anything
special to use /usr/sbin/sendmail for submission?
I'm seeing:

-rwxr-xr-x. 1 root root 213616 Dec 2 2011 /usr/sbin/sendmail.postfix
[root@svr001 mail]#
The man page says:
If you have Sendmail 8.12, then locally-submitted messages are
sent via SMTP, and MIMEDefang will be called for each resent
message. It is possible to set up Sendmail 8.12 so locally-sub-
mitted messages are delivered directly; in this case,
stream_by_recipient() will not work.
What do I need to tweak to make this work with Postfix? I'm running Postfix
2.6.6 and Mimedefang 2.73.
Thanks,
-Philip
