I'd not considered the possibility of using POP3 services without deleting read messages from the server. Leaving a copy on the server will absolutely run the resources use through the roof if enough folks do it. No sure how/if/why to limit frequent checks to "Download All Everytime" users except through Education (not an option in some cases<g>). >> In business, a "communication" often takes four or five retries. >Huh? It may only appear to take four of five retries _if_ people make >the utterly wrong assumption that e-mail is a real-time medium. Well, if you expect 5-minute turn-around, and GET 5-minute turn-around usually, a lot can be accomplished. If you DEPEND on 5-minute turn-around, you are asking for trouble and need to move toward instant messaging or the phone (or morse code, if that's the way you like it - I sure do). Thanks for the clarification.
