Heard about possible memory leaks with Mail, but for some reason, after I wake my MBP Mail drives the CPU's up full causing the cooling fans to come on, shuddering my battery and making a racket.

Anyone else experience this?

I had something similar and still on ocassion do but that was/is down to httpmail plugin.

Although once it happened on Tiger when it was downloading a rather large attachement.

What type of accounts do you have?
Can you see if they are have any large attachements waiting to download? (i.e. log into the email account over the web for example)
Do you have any plugins installed?
 
I know on Windows, Outlook used to do this, where it would get in a state where it would continually poll for new messages, eating up cpu cycles.

I wonder if some similar polling action is going on here with Mail?

I just had it happen to me yesterday. My friend sent me an email with a bunch of stuff off of Gutenberg in it. The issue is that they were all one long text, and he didn't attach it... so it was a few hundred thousands words long in a single email. With that email selected, Mail used 120% CPU, with it unselected, it went back down to almost nothing.
 
Apple really needs to work out these Leopard bugs. Mail is one of the biggest offenders IMHO, to the point where I don't use it anymore because I got tired of it crashing/hanging all the time.

They need to put down their friggin' iPhones and get back to work.
 
I am using an HTTP Plugin for Hotmail. Could be that maybe?

Hope they sort it out with 10.5.2.
 
This happens to me everytime I turn on my mac mail app.

I am using the http plugin and it's gotten so bad that I only run Mac mail once a day in order to archive my mail.

The fans run full speed, the mail program will never fully quit and it cuts my battery life in 1/2 - stinks!
 
I thought 110% was maximum anything could go. I guess athletes just aren't giving it all they have.:p
 
I don't use the HTTPMail plugin anymore, and I've not had any issues with Mail flipping out and taking up a lot of CPU usage since 10.5.3.
 
What do you use in place of the http mail plug-in? Did you abandon hotmail all together?
