------- Additional Comments From [EMAIL PROTECTED] 2004-10-23 23:56 ------- It appears that header requests with LWP can be done in about 0.10 to 0.20 seconds per resolution, on my cable connection anyway. Which while certainly is a long time, wouldn't be too bad on lower volume systems, if limited by the total number of lookups done per message (to avoid DoS). Does the URIDNSBL code run in parallel with anything else, or is it blocking? The downside is that it requires another dependency, LWP. Although it would be optional, as would turning on redirection resolution. To limit the processing hit, though, you could probably score the message based on the number of recursive redirects. I don't think any sensible user is going to redirect things more than twice, and probably not more than once in most cases. Scoring the number of redirection recursions would likely have the effect of spammers avoiding the use of recursive redirections, thus saving us on the processing time. Obviously you'd have to stop resolution recursions as soon as you don't recognize the redirector, though, since doing otherwise could register tracking bugs with a spammer controlled redirector. ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
