It is a good idea to report this on the postfix mailing list. I
don't have the time to read all the blogs, wikis, etc. on the
Internet that discuss Postfix.
Now that the problem has (finally) come to my attention, do you
have an example? I don't run software that barfs on nulls so this
is difficult to recreate and eliminate just fom a verbal description.
A hexdump of a message, and Postfix/Cyrus logging for that message
would be sufficient. You can send this off-list.
