Why could rapid mail checking be a DoS? - Typically, ISPs have *far* more customers than their servers can simultaneously handle. They rely on most of the customers not using the mail server at the same time, nor very frequently. If all their clients did that, or just too many of them, it ties the server up (a DoS to others trying to use it). Polling POP, or even IMAP, isn't a replacement for running your own SMTP server. I don't quite think the above was what you were asking about, but never mind. Someone else might find it useful, and I was trying to cover all the bases. Why is your client using heavy CPU checking for mail? - My guess is that spam assassin is looking at it coming through, checking against a plethora of rules. Evolution can get nastily heavy and slow at filtering mail, especially if you're also doing the remote checks. -- (This box runs FC5, my others run FC4 & FC6, in case that's important to the thread.)
