In all (5) of the hams I found, the IP was in IANA Reserved space

Most where in reserved space, but by no means all of them.

I checked 2.5 months worth of logs for my most diverse domain, and
found only 5 (out of 21392) hams with Message-IDs containing square
brackets around an IP address (all were as above).

Interesting. I searched only 30 days and about 6,000 emails and found 12 spam and 32 ham. Not all were bracketed. All the ham messages were to mailing lists.

Sorry, 60,000, not 6,000. (actually, 57,938 to be exact)

There were a total of 414 messages that matched having an IP in the message-ID having at most two characters between it and the EOL. I did not look specifically for square brackets when i did the search, just any IP at the end of the line with 0-2 optional characters, accounting for ]> or > or simply a bare number.

Of those 414, only 32 were tagged as being below 0 (I misremembered this as 'ham'), 12 above zero, and 0 where tagged as spam. The rest were not run through SA for one reason or another (mostly because most messages are not run through SA. However, looking briefly over those other 370 messages or so, they aren't spam, they are almost all mailing list messages). I see maybe as many as 20 messages that might be spam.

here are some matches:

Message-ID: <25da2352a681b94e1e0f3b2873d4...@66.228.123.6>
Message-Id: <2009040333459.330.483228534.sw...@65.40.129.19>

Message-Id: <c4fb7453e5818b059ff369df18ce...@66.228.123.6>
Message-ID: <c4fb7453e5818b059ff369df18ce...@66.228.123.6>

(I removed a random character from each message-id just in case)

Keep in mind though that my postfix settings are fairly restrictive and that I drop zen listed connections during the transaction phase, so I tend to have less spam hitting SA than a lot of systems. Also, once messages are identified as coming from a mailing list, they are not run through SA at all.
