Email always searching for new messages


Hi guys,
Any idea why when i installed my Dreamhost email into Apple Mail it will be always, i mean 24 hrs a day searching for new messages. It didn’t happened in my last computer. I did change the settings to manual email download for that account but it keeps the same.

I know is no major problem but certainly annoying and maybe bandwidth consuming as well.

Here is a picture (my email account is under the blue rectangle) but you get the idea.

thanks for any info.
