Hi,

 

I have upgraded to Mountain Lion and it would be perfect if there was one major issue fixed: when having Mail.app open, this application uses between 80 to 110% of the CPU power constantly. The main issue is reduction of speed of other operations but more concerning is that fan colling fan just runs endlessly.

 

Has anyone experienced such issue? The activity Monitor shows that Mail uses all processing power.

 

I use a macbook 13' (unibody) and Mail has an Exchange mail account active (and the iCloud email). After upgrading I recreated all mailboxes (by deleting the V2 folder), server setting is using SSL and no SASL.

 

Could it be a bug or something in the server settings/account setting?

 

Y.

MacBook Pro, Mac OS X (10.7.3)
