For anyone that wants to send out mail from ColdFusion
with hashcash, it's not hard. Here's some example code:
Didn't take much to get this working. There is
a command line executable at hashcash.org that
you can download. So, (after removing buncha
dynamic stuff for clarity here) it looks like this:
<CFTRY>
<CFEXECUTE
name="c:\hashcash.exe"
arguments="-mb22 user@xxxxxxxxx"
variable="hashCashResult"
timeout="5">
</CFEXECUTE>
<CFCATCH type="Any">
<CFSET hashCashResult="">
</CFCATCH>
</CFTRY>
<CFMAIL
TO="user@xxxxxxxxx"
FROM="me@xxxxxxxxxx"
SUBJECT="Password Reminder" >
Hello user,
The password for your account is: some_password
Cheers,
The Database
<CFIF Len(hashCashResult) NEQ 0>
<cfmailparam
name = "X-HashCash"
value = "#hashCashResult#" >
</CFIF>
</CFMAIL>
Here is how much SpamAssasin adjusts the spam score based
on the number of bits used (22 in the above example)
Hashcash 20 bits -0.500
Hashcash 21 bits -0.700
Hashcash 22 bits -1.000
Hashcash 23 bits -2.000
Hashcash 24 bits -3.000
Hashcash 25 bits -4.000
Hashcash >25 bits -5.000
Cheers all,
Anders
