OK, so we're talking about the SC webmail interface, and no, I don't think you're doing anything wrong. I think it has to do with some oddities of the IMP/Horde webmail system that SC uses and the multiple ways that email messages can be formatted (and mis-formatted).
Here are some details...
When a message arrives in your INBOX with Content-Type headers info like this:
Content-Type: multipart/alternativeand the message body only contains an HTML section labled like this:
Content-Type: text/html;
Content-Transfer-Encoding: quoted-printableand there's no additional plain text portion, then SC webmail will display:
There are no alternative parts that can be displayed inline.So, it's refusing to show you the HTML body of the email because there isn't an accompanying "text/plain" section.
If, OTOH, a message with the "multipart/alternative" type shows up with both "text/html" and "text/plain" sections in the body, then you'll actually get to see the plain version on the webmail screen, and above it, will be "
Alternative parts for this section:" and a link to the html section.
If, however, the content type in the headers is:
Content-Type: text/html; charset=us-asciiand the message only contains html, then the webmail interface displays a link for "unnamed" [text/html] (which you may click on and view) and then "
There are no parts that can be displayed inline."
I haven't found any settings that will make the webmail system display the parts of messages that it currently refuses to display, and from my reading of the Options (Options : Message Viewing), I think that there might be something wrong with SpamCop's installation/implementation of IMP. On those messages in your INBOX that you're referencing, IMO you
should be allowed to view the contents, but on a "multipart" message with only an HTML section, there doesn't seem to be a way to view the HTML portion in the webmail interface, even if you want to.
I'll let some of the other long-time webmail users chime in now, because I might not be entirely correct.
