bounces SMTP error 554
I have a couple members of our list whose remote mail servers reject some of our messages because of what appears to be text formatting in the messages. Usually MS Office formatting. I get a bounce back ala:
"host mtaonline.net.mx1.greymail.rcimx.net [208.80.206.74] SMTP error from remote mail server after end of data: 554 Failed: Malformed MIME field: X-Ham-Report: Spam detection software, running on the system " gandalf.nomekennelclub.com", has NOT identified this incoming email as spam. The original message has been attached to this so you can view it or label similar future email. If you have any questions, see root\@localhost for details. Content preview: blockquote, div.yahoo_quoted { margin-left: 0 !important; border-left:1px #715FFA solid !important; padding-left:1ex !important; background-color:white !important; } 3 topping 19 inch pizza$20.00 2 chicken fajitas and a sala [0xC2] ..."
In googling, it seems I found others have problems with the [OxC2] type formatting as well. Just curious if there's much I can do about it or just ignore these bounces.
Here's the original source of that particular message:

It looks to me that the issue causing the bounce is not the content of the message body, but rather it is that spam detection software running in some MTA in the delivery chain is adding the headers something like

to the message and the added headers are either non-compliant because they are too long or not properly folded or contain non-ascii characters.
It may be that whatever doing this is rendering the HTML body for the Content preview: and turning the html entities into utf-8 0xC2 0xA0 which is the two-byte utf-8 representation of the "no break space", but if it is putting those bytes (represented perhaps as "[0xC2] ...") into a Content preview: header, that is definitely a problem and something at gandalf.nomekennelclub.com is not doing the right thing.

If you don't control gandalf.nomekennelclub.com, there's probably not much you can do beyond ignoring the bounces if they're infrequent enough that user's delivery isn't being disabled (or raise bounce_score_threshold if necessary)

It's hard to tell a lot from this without seeing the actual raw message without it's being wrapped, folded, whatever by your MUA. Note that the initial "7=C2=A0 " part looks like a quoted-printable encoding, presumably from the text/plain alternative part that corresponds to the "7 </div> " at the end of the html alternative part below.

I do have control over gandalf - a VPS server (so that much, at least). Not sure how I would obtain an "actual raw message" other than what I received from the sender as a subscriber myself. The server uses Exim and is a CPanel installation.
Seems like I get these bounces a couple a day and so far not often enough increment to suspend the guys that these are bounced from.
thanks for your help! /jim

The entire raw message you received from the list would be fine. It appears that you are using googlemail. If this is the case, if you are viewing the message, click the downward triangle "more" icon next to the "reply" icon near the upper right (not the one in the toolbar above that) and select "show original". That text is what I'd like to see in its entirety and without being folded or wrapped.
