My users complain if it's not (soft) real-time, and rightly so For most users, it's more real-time than a fax transmission because both parties need not walk to the fax machine. Today, even an MX hop which performs virus scanning adds a latency of well under a second (if configured properly). Anyway, today a lot of spam is already sent through webmail providers with poor registration procedures and no spam controls, and these services definitely have queues. Greylisting would affect them. It helps with the current generation of zombie software, but there are solutions of comparable effectiveness which do not introduce artificial delays. In a few months, zombie software will have been extended to use virtual queues, so greylisting will be mostly ineffective. It may make sense to switch on greylisting for mail servers in address space with automatically generated reverse lookup, though. Sort of a compromise. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
