First, thanks Rick and Sandy for the responses. I really appreciate the additional feedback. IMail has been great about giving us 95% of the functionality we need for the messaging portion of our online educational suite. It's that last 5% that's getting us.

I thought about doing it that way, but I read that there was a limit: "Each delivery rule is limited to 5000 characters." http://www.ipswitch.com/support/IMail/guide/imailug7.1/Chapter%205%20process ing3.html I guess depending on the email address sizes, this is roughly a maximum of 200 contacts. For most student accounts, this should be just fine. However, I'm expecting the teachers and administrators to require the same filtering feature. If a school has approximately 500-1000 students, with roughly 1000-2000 parents... a school administrator would need a filter rule that was in the neighborhood of 40,000 characters (~25 char per email address), teachers would need about 150 contacts for students and around 300 contacts for their parents (~10,000 characters). The teachers are also the users that would actually use the submailbox destination most. For example... Period 1 Students Folder, Period 2 Folder,... Period n Students Folder. I guess for now, we can't have our cake and eat it. It's either A) lose the submailbox functionality or B) keep the incoming contacts list to less than 5000 characters. Which actually brings up an interesting academic question. Which is more processor/memory intensive for filtering, say, 100 contacts? The positive search (line by line) or the negative search (all on the same line)?
