Mail - deleting messages when have multiple Macs connecting to same accounts

I have an iMac, macbook and iPhone all set to grab mail from:
Gmail x 2 - IMAP
Yahoo - POP
Work Exchange server - IMAP
Personal server - IMAP
Hotmail - POP

When I delete a message on one machine, I would love to be able to have that message removed from all machines. Can't figure it out though... Seems the Gmail IMAP does the job pretty consistently. Others have messages left there.

Appreciate the help

Never mind
Changed Yahoo to IMAP and hotmail to Exchange and it works now
