Good morning,
I've been running Spamassassin since 2.43 and we are quite happy with it.
I just finished an upgrade from 2.55 to 2.60 and seemed to go well. I
upgraded two servers, boith configured identically, with same software,OS,
etc installed.
SPARC 20, Solaris 2.6
Spamassassin 2.60
qmail 1.03
Vpopmail 5.3.20
snprintf 2.2
Perl 5.6.1
Both boxes handle 400k to 500k messages a day total, scanning nearly 40% for
spam and have been handling the load quite well.
After the upgrade I noticed one box had the following errors show up in
the spamd log,
----------------------------------------------------------------

-----------------------------------------------------------------
Looking at SpamAssassin.pm it would appear that SpamAssassin is not
getting the username when the message is being passed off by spamc to
spamd and the errors are all a result of that issue.
I am passing the message to spamd with the following script in a
.qmail-<user> file. It is a modified version of ifspamh.sh and has worked
very well since 2.43.
------------------------------------------------------------------
#!/bin/sh
# spamc - client location
SPAMC=/usr/local/bin/spamc
# qmail's forward program location
INJECT=/var/qmail/bin/qmail-inject
# mess822 822field location
M822FIELD=/usr/local/bin/822field
SPAMBOX="$1"
DELIVER="$2"
SENDER="[EMAIL PROTECTED]"
# we used to skip 'From ' - the 1st line that got added by spamd/spamc
# but it seems newer versions don't add it (and SA 2.50 adds a 3 line
# Received header)
output="`$SPAMC -f -d 127.0.0.1 -u $DELIVER| sed '1{/^From .*/d;}'`"
exitcode=$?
# spamc will not process a "large email"
msize=`echo "$output" | wc -c`
# there's also a sizelimit with some shells that triggers around the 512kB mark
# with an external printf and arguments size so we stop at this point
if [ $msize -gt 250000 ]; then
# probably deemed too large anyway .. let it through
exit 0
fi
flagvalue=`echo "$output" | $M822FIELD X-Spam-Flag | sed 's/^ //'`
# X-Spam-Flag might contain "YES"
if [ "$flagvalue" = "YES" ]; then
# match - likely spam
# no match - not a spam
# forward on the email
echo "$output" | $INJECT -a -f "$SENDER" $SPAMBOX
if [ $? -eq 0 ]; then
# so qmail will not do any further deliveries in .qmail file
exit 99
fi
# problem calling inject - temp failure
exit 111
else
# spamc doesn't distinguish temporary failure
# if we're passing through the message
# so look for signs that spamd provided the output..
flag2value=`echo "$output" | $M822FIELD X-Spam-Status`
exitcode2=$?
if [ $exitcode2 -ne 0 ]; then
# X-Spam-Status header not present in message -> failure of spamc/spamd?
# spamc will not process a "large email", but this is accounted for above
# so indicate temporary failure
echo "spamc returned temporary failure"
exit 111
fi
# indicate that qmail should continue processing dot-qmail file
exit 0
fi
----------------------------------------------------------
spamd is launched with the following run file from daemontools.
----------------------------------------------------------
#!/sbin/sh
PATH=$PATH:/usr/bin:/usr/local/bin
exec /usr/local/bin/softlimit -a 20000000 \
/usr/local/bin/spamd -c -v -u vpopmail -s stderr -L 2>&1
------------------------------------------------------------
I suspected at first that I had a .qmail-<user> file calling spamc without
the $DELIVER arg, hence no user value. I checked and every .qmail-<user>
file has a valid entry in vpasswd. They do, I have no orphaned .qmail
files.
I am at a loss to find a cause, any thoughts?
