Syncing Mail Issue

[NotOwning]

I have the iPhone 3GS and I'm using the mail application on the MacBook to get my mail from my new college email. I use my phone to get the email from that email as well. The problem I'm having is that whenever I delete an email on my computer it won't show that it has been deleted on my phone and vice-versa. Using my two yahoo emails I've been fine, and haven't seen this problem, but with this new college email, and using the mail application I can't get the mail to sync between the two devices.

Thanks in advance

I think Yahoo use IMAP this why it always in sync. I have the same problem with my work email, as they still use POP3, so when i delete an email from the iphone or the mac it doesn't show up in the other. So maybe it is the same case with your university email.
