I figured clients would have a way to > limit that, but I don't really pay attention to POP3 clients... The few clients I looked at didn't give any option to specify how many remote messages I want to retrieve, so I think defaulting to 50,000 is not the right approach. Maybe the default limit should be something "last 7 days or 1000 messages, whichever is larger"? My initial target for deploying POP3 support is to allow Gmail users to pull-subscribe to mailing lists, since Gmail is the #1 provider that we have trouble with message delivery due to their draconian threshold limits. However, I think if the default behaviour results in dumping 50,000 messages into people's inboxes, they wouldn't use it, which is why I think we should have a default that is lighter both on the server side and on the users. -K
