Sorry I'm behind on dovecot email.
Looking at http://www.buoy.com/pipermail/weather/2005-November.txt It appears that they're using some software to deliberately mangle the email address in the From line (both of them) so that they can post them on the web and not make it easy for the spam bots to harvest the addresses. That's no longer a valid From<space> line and the syntax of that line is very picky.
You'll probably have to write a script to restore the original From lines. For example, you'll need to replace <space>at<space> with @

Using dovecot-0.99.13-4.FC2
I grabbed a bunch of Mailman archive files from the Weather mailing list here:
http://www.buoy.com/pipermail/weather/
I gunzipped the older ones, then concatenated them all in correct order to create one big mbox file. I dropped it into my ~/mail folder and started my IMAP client (Mulberry) and opened the new Weather folder. It shows one gargantuan concatenated message, instead of lots of more reasonable-sized ones.
The messages appear to be properly separated by "<linefeed><linefeed>From<space>". Why doesn't dovecot parse them into separate messages?
I double-checked and removed any header lines with Content-Length, X-UID, X-IMAPbase, and X-Keywords. So this should look like a new mbox file with new content delivered by procmail. What's confusing dovecot?
