I was trying to post this to Bugzilla but getting a software error. 
Might want to fix bugzilla.


  Software error:

DBD::mysql::db do failed: Access denied for user 'bugs'@'localhost' to 
database 'bugs' at Bugzilla/DB/Mysql.pm line 213
Bugzilla::DB::Mysql::bz_lock_tables('Bugzilla::DB::Mysql=HASH(0x8a11464)',

'keywords WRITE', 'dependencies WRITE', 'bugs_activity WRITE', 'groups 
READ', ...) called at /usr/local/www/data/bugzilla/post_bug.cgi line 410

For help, please send mail to the webmaster 
([EMAIL PROTECTED] 
<mailto:[EMAIL PROTECTED]>), giving this error message and 
the time and date of the error.

Here was my message.

I hope you can get this in before the next release because with this 
feature and the new one Graeme added to test without counting I can 
write a REALLY good greylisting system.

What I need is a "forget" command that will allow me to erase 
information from the time limiting database base on a key.

warn condition = some condition
     ratelimit = forget / key

Here's a quick overview of using ratelimit to do grey listing. Real 
email server will try/retry from lowest numbered MX records going up. 
Spambots generally don't retry and often start with the highest MX 
record or random MX records. So - imaging one computer with 3 IP 
addresses, all of which are MX.

The lowest MX returns DEFER on new connection but the ratelimiting 
remembers that so that for the next hour if they come back to the second 
MX or the first MX they are both open. Generally a real server will his 
the second MX in a fraction of a second of the first one. So in order to 
get a message into the system the lowest MX has to be touched and then 
it is unlocked.

However the third MX (or several more higher) should never be touched 
and if they are I want to be able to forget and good credits in the 
system and perhaps replace it with a different key that is a penalty 
key. Or if the sending server does something right I want to forget the 
penalty keys.

I have a rough plan figured out based on modifying what I'm already 
doing and I think the ability it forget keys would be useful. So I'm 
hoping that forget is something easy and that you could just throw it in 
before the next release of Exim if it's something that's not too much 
trouble.
