World: r3wp

So, there is no nslookup utility for rebol ?

must be http://www.compkarori.com/soap/index.shtml

you lost me ...

print read dns://www.coolnamehere.com/

or is that not what you were thinking of?

hmm.

that is what I was looking for

I want to find the mail server for a given email address...

so I can implement outgoing smtp mail ...

finger? whois?

I'm behind a firewall, so I don't know which (if either)

read join dns:// mailhost

but how do you know the mailhost ?

from the part agrer the @ in the email address I wouls think

after

nope ..

I have an email ... [gchiu-:-compkarori-:-com] .. 
How would you get the MX record for that?

... trying to find something useful right now :-)

this is the answer : 203.79.110.37

because I know it :)

leave me a message here if you find anything :)

Will do :-)

http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=dig.r
maybe?

Dig.r does appear to support MX...

ahh... I looked for digger but not dig

Doesn't give me the correct answer :(

what about
	read dig://www.comparori.com/MX

.oO(firewalls are annoying at moments like this)

hey, that works :)

good, had to guess my way through in my head :-D

Now I can start coding my smtp server for outgoing mail.

actually, this is the form I used

oh, the www was confusing it?

yeah ..

Graham depends on the tool. With dig. You do
dig MX domain.dom

what does this mean?


   * Generate 64 bits of randomness from a good, well-seeded random 
   number generator;

ie. how large a seed do I need to get 64 bits ?

http://www.jwz.org/doc/mid.html
	

 In summary, one possible approach to generating a Message-ID would 
 be:

    * Append "<".


    * Get the current (wall-clock) time in the highest resolution to 
    which you have access 

    (most systems can give it to you in milliseconds, but seconds will 
    do);


    * Generate 64 bits of randomness from a good, well-seeded random 
    number generator;


    * Convert these two numbers to base 36 (0-9 and A-Z) and append the 
    first number, 

    a ".", the second number, and an "@". This makes the left hand side 
    of the message ID be only about 21 characters long.


    * Append the FQDN of the local host, or the host name in the user's 
    return address.

    * Append ">".

enbase doesn't accept a value of 36

I used 1'000'000 here .. don't know if it's enough

    generate-messageid: does [

     rejoin [ "<" enbase form now/time/precise "." enbase form random 
     1000000  "@" server-name ">"]
	]

basically you need 13 random characters, don't you?

I"m not sure ...

where does the 13 come from?

a 64 bit number has 64 digits in base 2, and 12-13 digits in base 
36

anyway, since you just need some randomness, a random 12 character 
string will do

so use base 32 ?

>> s
== "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ"
>> pool: "" insert/dup pool s 12
== ""
>> random/seed now
>> copy/part random/secure pool 12
== "GQOTTWDZZXNL"
>> copy/part random/secure pool 12
== "JOFF6QY4T2H8"
>> copy/part random/secure pool 12
== "8RJ2MFTQ0IJQ"
>> copy/part random/secure pool 12
== "ZKCS1DX7UTHL"
>> copy/part random/secure pool 12
== "DY3VJH4UTNFF"
>> copy/part random/secure pool 12
== "KWPNQRIJ40KN"

note that "well seeded" usually means you're seeding from some truly 
random value, rather than the current time

I guess since I'm not processing that many email, it doesn't have 
to be truly random.

i think that for your purposes, enbase/base 64 would be just fine

so you could use something like:
