WrongMX from amavisd-new?

[McDonald, Dan]

I installed WrongMX.pm today, on my secondary MX, but it does not appear
to be firing.  A spamassassin -D --lint does show the module to be
loaded, and the module shows up in my amavisd-new logs:

Jul 23 13:33:56 foo amavis[17285]: (17285-01) extra modules
loaded: /etc/mail/spamassassin/Botnet.pm, /etc/mail/spamassassin/FreeMail.pm,
/etc/mail/spamassassin/RelayCountry.pm, /usr/lib/perl5/5.8.7/i386-linux/auto/Storable/autosplit.ix,
/usr/lib/perl5/vendor_perl/5.8.7/Mail/SpamAssassin/Plugin/WrongMX.pm,
Mail/SpamAssassin/CompiledRegexps/body_0.pm,
Mail/SpamAssassin/Plugin/PDFInfo.pm, Regexp/Assemble.pm, Storable.pm


Amavisd-new adds a received header from localhost - would that be
confusing the WrongMX.pm plugin?  I tried to use-the-source to figure
out what it was doing, but got lost...

WrongMX plugin needs a recipient address, and tries to fetch it from
a username under which spamassassin command is run, or by using a
signal_user_changed mechanism (option -u in spamc).

In the amavisd environment, SpamAssassin always runs under one
username (e.g. vscan), and the $self->{main}->{username} as used
in wrongmx.pm always returns 'vscan', with no domain, which
makes it useless to its purpose and it bails out. Another problem
is that wrongmx expects exactly one recipient, but a mail
message may have multiple recipients.

Amavisd does pass a list of recipients to SpamAssasin as
synthetic header fields X-Envelope-To (there may be more than
one such header field). WrongMX would need to be modified
to be able to deal with multiple recipients, and to collect
them from X-Envelope-To.

Mark, I'm running WrongMX on my home server. My secondary MX is
zoneedit.com. I'm runniong sendmail, spamass-milter and sa. My
configuration for sa is this:

loadplugin      WrongMX wrongmx.pm

header          WRONGMX eval:wrongmx()
describe        WRONGMX Sent to lower pref MX when higher pref MX was up.
tflags          WRONGMX net
score           WRONGMX 1.0

I'm at a loss to figure out how to tell WrongMX what address it thinks it
should know is my secondary MX (or which is the primary, for that matter).
Is WrongMX supposed to be able to figure it out? I've had it installed now
for about a month and it has not caught anything that was first sent to my
secondary.
