People forget to even have DNS setup on their Toaster, as Matt has said before. If someone forgot to configure DNS, chances are, little or nothing will work -- from port fetching to timely mail delivery.

How about adding a simple DNS check to the Toaster Setup test suite? And in the meantime, you could give some sort of crude benchmark, depending on the circumstances of the test data.  I am not looking for something too hefty, but something small and sturdy to make sure there is a good DNS server around answering queries reasonably fast.

Here is a sample of some DNS lookups you could perform.  What I would envision is that there were around 20 to 100 forward and reverse lookups, and that the lookups were timed.  I guess you could look them up in parallel, and wait a maximum of around 15 seconds for all of the replies.  The interesting thing about a lot of reverse lookups is that they often fail because no one has published them.

Iteration 1: lookup A records.
Iteration 2: lookup NS records.
Iteration 3: lookup MX records.
Iteration 4: lookup TXT records.
Iteration 5: Repeat step 1, observe the faster response time due to caching.

Here's a sample output!  Wow.

Your DNS Server (or its forwarder) seems to be caching responses. (Good)

Do DNS records agree on all DNS servers?  Yes. identical.
Skipping SOA match.

I have discovered that testmydomain-local.net has no MX records.  Shame on you, this is a mail server!  Please fix this issue and try again.

I have discovered that testmydomain-local.net has no TXT records.  You may need to consider an SPF v1 TXT record.

Here is a dump of your domain records I dug up for you:
xoxoxoxox

Does hostname agree with DNS?  Yes. (good).

Is this machine a CNAME for something else in DNS?  No.

Does this machine have any A records in DNS?  Yes.
smtp.testmydomain-local.net is 192.168.41.19.  This is a private IP.

Round-Robin A Records in DNS pointing to another machine/interface?
No.

Does this machine have any CNAME records in DNS?  Yes. aka
box1.testmydomain-local.net
pop.testmydomain-local.net
webmail.testmydomain-local.net

***************DNS Test Output complete

Sample Forwards:
The first few may be cached, and the last one should fail.  Some will have no MX server, some will have many.  (The second to last entry has an interesting mail exchanger and priority.)  Many of these will (hopefully) not be found in even a good sized DNS cache.

I have purposely listed a few more obscure entries to try to get the DNS server to do a full lookup.
localhost
<vpopmail_default_domain if set>
www.google.com
yahoo.com
nasa.gov
sony.co.jp
ctr.columbia.edu
time.nrc.ca
distancelearning.org
www.vatican.va
klipsch.com
simerson.net
warhammer.mcc.virginia.edu
example.net
foo.com
example.impossible.nonexistent.bogus.co.nl

[need some obscure ones that are probably always around, plus some non-US sample domains.]

Sample Reverses:
Most of these should be pretty much static.  Border routers, nics and such.  I was looking for a good range of IP's from different continents and providers.  Help needed in some networks.  I didn't try to include many that don't have a published reverse name, but many examples exist in case you want to purposely have some.

[Looking to fill in some of the 12s, 50s and 209s better.  Remove some 198s]

Just a little project.  I'm not sure how I could code it, but it is a little snippet I have been thinking about.  I figure that if you write the code once, it would be quite a handy little feature to try on a server you are new to.

=item email_send_attach


  ######### email_send_attach ###############
  # Usage      : internal only
  # Purpose    : send an email with a .com attachment
  # Parameters : an email address
  # See Also   : email_send

Sends a sample test email to the provided address with a .com file extension. If attachment scanning is enabled, this should trigger the content scanner (simscan/qmailscanner/etc) to reject the message.


=item email_send_clam

Sends a test clam.zip test virus pattern, testing to verify that the AV engine catches it.


=item email_send_clean

Sends a test clean email that the email filters should not block.


=item email_send_eicar

Sends an email message with the Eicar virus inline. It should trigger the AV engine and block the message.


=item email_send_spam

Sends a sample spam message that SpamAssassin should block.
