So our students can access their E-mail from outside via the Web. Easy enough no problem. However there is the flexibility to make it much easier by allowing them IMAP access and direct Blackberry access (BES/BIS server built in).
Does anyone else do this? I'm just thinking about the posibilities for misuse even though I've got it configured so that the sender E-mail address must match the authentication credentials and you must authenticate to send mail. I'm just being cautious as I don't want any situations where a pupils sends a message "from" the Head or similar.
What do you do, any pitfalls I should be extra careful of?
