You nailed it, Ben. Thanks!
I downloaded/installed the dovecot-dev package from the same maintainer
and was able to build Antispam without issue.
The hang-up now seems to be with my configuration.
I'm seeing the following error in my email client whenever I attempt to
move an email message from, say, Inbox to Junk folder:
[SERVERBUG] BUG Unknown internal error.
Nothing at all appears in syslog when this happens.
I followed the instructions at http://wiki2.dovecot.org/Plugins/Antispam
, to the letter, I believe.
The relevant portions of my configuration are as follows:
---------------------
protocol imap {
mail_plugins = quota imap_quota antispam
}
plugin {
quota = dict:user::file:/var/vmail/%d/%n/.quotausage
sieve = /var/vmail/%d/%n/.sieve
antispam_backend = MAILTRAIN
antispam_mail_sendmail = /usr/bin/sa-learn-pipe.sh
antispam_mail_spam = --spam
antispam_mail_notspam = --ham
antispam_spam_pattern_ignorecase = spam;junk
}
---------------------
The permissions and execute bit are set in accordance with other
executables in the same directory:
# ls -lah /usr/bin/ | grep -i "sa-learn-pipe.sh"
-rwxr-xr-x 1 root root 297 Sep 5 11:17 sa-learn-pipe.sh
I would provide more log content, but the debug options seem to be gone
in the forked, >= 2.0 version of this plug-in.
Any ideas are very much appreciated.
Thanks,

Given that nobody shared any insight here, I decided to stand-up a
completely new VM with Ubuntu 12.04 LTS and see if the same error occurs.
While the error is different this time around, I am still unable to get
any variant of the dovecot-antispam plug-in working.
When I attempt to use the current packages from Ubuntu 12.04.1 LTS, and
I use the above configuration, my syslog fills-up with the following:
dovecot: imap-login: Login: user=<u...@example.com>, method=PLAIN,
rip=10.0.1.57, lip=10.0.1.8, mpid=2879, TLS
dovecot: master: Error: service(imap): child 2879 returned error 3
Surprisingly, I can find only two other mentions of "error 3" anywhere
on the Internet. Those mentions were from another user to this mailing list:
http://www.dovecot.org/list/dovecot/2012-August/067787.html
http://www.dovecot.org/list/dovecot/2012-August/067814.html
The lack of "error 3" ubiquity leads me to believe that I must be doing
something stupid.
There's no question that this behavior is related to the
antispam-plugin, because when I commented-out the relevant lines in
Dovecot's configuration file, the error does not occur.
I have followed the instructions at
http://wiki2.dovecot.org/Plugins/Antispam to the letter, and this is the
result.
The only instance in which I diverged from the Wiki article is that I
used the Ubuntu-provided dovecot-antispam package (instead of compiling
the plug-in from source).
I am trying to use the "mailtrain" back-end, per the above-cited Wiki
article, to call SpamAssassin's "sa-learn" utility for real-time learning.
I am not using the SpamAssassin daemon (spamd).
I'm about to throw in the towel on this plug-in, so any help would be
greatly appreciated.
Thank you,

I've never used this plugin but let offer up my home brewed script that
I call from crontab:
# Process and delete .Spam and .Ham Maildirs
11 */4 * * * /usr/local/sbin/maildir.sa-learn
and /usr/local/sbin/maildir.sa-learn:
#!/bin/bash
MAILDIR=Maildir
LS=/bin/ls
RM=/bin/rm
SU=/bin/su
FIND=/bin/find
SALEARN=/usr/bin/sa-learn
for i in `$LS /home`; do
prefs="/home/$i/.spamassassin/user_prefs"
# [ ! ."$i" == ".bill" ] && continue
echo $i
spamdir="/home/$i/$MAILDIR/.SystemFolders.Spam"
[ ! -d "$spamdir" ] && continue
$SU -c "$SALEARN --prefspath=$prefs --spam $spamdir/new" $i
$FIND "$spamdir/new" -type f -delete
$SU -c "$SALEARN --prefspath=$prefs --spam $spamdir/cur" $i
$FIND "$spamdir/cur" -type f -delete
hamdir="/home/$i/$MAILDIR/.SystemFolders.Ham"
[ ! -d "$hamdir" ] && continue
$SU -c "$SALEARN --prefspath=$prefs --ham $hamdir/new" $i
$FIND "$hamdir/new" -type f -delete
$SU -c "$SALEARN --prefspath=$prefs --ham $hamdir/cur" $i
$FIND "$hamdir/cur" -type f -delete
done
With my setup each user has their own spamassassin user_prefs and bayes
tokens.
