mutt destroying formatting of spamassassin headers

[Marc Haber]

Hi,

mutt destroys the formatting of spamassassin's report inserted into
the header. I don't remember for how long this has been happening, but
it has started to annoy me.

Here is what is in the maildir (looked at with less):

|X-Spam-Report: torres.zugschlus.de
|
| Content analysis details: (-6.8 points, 5.0 required)
|
| pts rule name description
| ---- ---------------------- -------------------------------------------
| -5.0 RCVD_IN_DNSWL_HI RBL: Sender listed at http://www.dnswl.org/, high

| [82.195.75.100 listed in list.dnswl.org]
| -0.0 RCVD_IN_MSPIKE_H3 RBL: Good reputation (+3)
| [82.195.75.100 listed in wl.mailspike.net]
| -0.0 RP_MATCHES_RCVD Envelope sender domain matches handover relay domain
| 0.0 HEADER_FROM_DIFFERENT_DOMAINS From and EnvelopeFrom 2nd level mail
| domains are different
| -1.9 BAYES_00 BODY: Bayes spam probability is 0 to 1%
| [score: 0.0000]
| 0.1 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid
| -0.0 RCVD_IN_MSPIKE_WL Mailspike good senders
| 0.0 T_DKIM_INVALID DKIM-Signature header exists but is not valid

And this is what mutt displays:

|X-Spam-Report: torres.zugschlus.de Content analysis details: (-6.8 points, 5.0
| required) pts rule name description ---- ----------------------
| ------------------------------------------- -5.0 RCVD_IN_DNSWL_HI RBL:

| necessarily valid -0.0 RCVD_IN_MSPIKE_WL Mailspike good senders 0.0
| T_DKIM_INVALID DKIM-Signature header exists but is not valid

In the spool, the line breaks are 0x0a in header and body (hexdump -C
on the maildir file), and it looks like mutt is collapsing whitespace
into spaces and then re-flowing the header.

The body just displays nicely.

Is there any muttrc setting that I might have inadvertently used,
breaking my display?

Using mutt 1.7.2 (which identifies itself as NeoMutt) from Debian
stable.

For what it's worth, mutt is displaying the "unfolded" version of
the SMTP header field (RFC 5322). Maybe knowing the terminology
will help find something in mutt's documentation.

My gut reaction is that Spamassassin shouldn't try to present
formatted information in a mail header. It wouldn't surprise me if
the RFCs say the folding carries no information (but I can't be
bothered to check).

It helped me find #3135, fixed in 1.5.18. I do have 1.7.2, so the fix
should be in there, but neither ":set wrap=0" nor "set wrap_headers=0"
do change displaying of the spamassassin header.

The docs suggest that both settings only affect outgoing mail, but
that's not my issue. I want mutt not to destroy the (admittedly not
very rfc compliant) formatting of the header when _displaying_ a
message.
