Thanks everyone for the pointers. Yes, the test message did not bounce, 
but two of the original OP messages did. The same thing happened on some 
of the spamassassin list mails as well with the same error message.

postconf -n returns...
strict_8bitmime = yes
strict_rfc821_envelopes = no

No mention of   strict_8bitmime_body   listed.

I believe this is standard Suse postfix setup, I did not change this 
setting. I am using Cyrus IMAP, does this have any bearing on this matter?

Will changing strict_8bitmime = no in /etc/postfix/main.cf (and postfix 
reload) likely fix this problem? Any repercussions with Cyrus?

Also, if you have time, what is the purpose of making this setting to 
yes? I take it that it prevents malformed email of some sort. But what 
is the drawback to not having this check set to strict? What are the 
known sloppy email clients (er, Outlook Express??!!).

Many thanks,

Jim Flanagan
