Description Kurt Huwig 2003-10-10 06:07:01 UTC 
Your bugzilla uses 'bugzilla@bugzilla.spamassassin.org' as sender address. This
domain has no MX:

kurt@leeloo:~> host -t mx bugzilla.spamassassin.org
kurt@leeloo:~> nslookup
> set q=mx
> bugzilla.spamassassin.org.
Server:         192.168.0.254
Address:        192.168.0.254#53

Non-authoritative answer:
*** Can't find bugzilla.spamassassin.org.: No answer

Authoritative answers can be found from:
spamassassin.org
        origin = spamassassin.org
        mail addr = postmaster.spamassassin.org
        serial = 2003072901
        refresh = 86400
        retry = 3600
        expire = 604800
        minimum = 86400

Therefore our mailserver does not accept mail from your bugzilla:

INFO: Connection accepted from bugzilla.spamassassin.org (64.142.3.173)
Oct 10, 2003 2:59:12 PM de.ikuag.sponts.filter.DomainHasMX doFilter
FINE: domain bugzilla.spamassassin.org has no MX
Oct 10, 2003 2:59:12 PM de.ikuag.sponts.action.TarpitAction execute
INFO: NO TRANSACTION: tarpitting for 900 seconds

This means that a whole bunch of people in the anti-spam community cannot use
your bugzilla.

MX records aren't required.  I should set some up though since we have
a backup mx for bugzilla...

But it does have an A record, which is valid.

--j.

You must be kidding, this is definitely a bug in the tarpit.
Using an A record is perfectly valid.
Comment 4 Theo Van Dinter 2003-10-10 11:56:40 UTC 
I'm closing this as invalid since it 1) has nothing to do with SpamAssassin, and 2) as both quinlan 
and myself have stated, not having MX records is not an error.

However, I did add MX records this morning as bugzilla has a backup host that wouldn't have been 
used without the records.

If you are, in fact, blocking mails from hosts/domains w/out MX records, you're likely getting 
heavy numbers of false positives.  fyi.
Comment 5 Aaron Sherman 2003-10-14 14:08:26 UTC 
Tisk, tisk. Your mail filtering should be based on a more sophisticated set of
metrics that involve some sort of... I dunno... weighted scoring of individual
factors... perhaps something with an extensible ruleset... I'm just thinking out
loud here, of course, there's no such tool. What is SpamAssassin? That... that
was a pigeon!
