<rant> This is one of the reasons callbacks are evil (apart from the extra network loading). They just don't scale. There are a bunch of supposed "antispam" measures which are bigger problems than that which they purport to solve. C/R and callbacks fall into this camp - especially if someone really is the victim of envelope forgery attacks (Callbacks and C/R have been known to effectively cause DDoS on smaller mailservers) </rant> ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
