Help Desktop email client stopped working after DROID2 synch'd


Aloha, I really like my cell phone but once I synch'd my email on the Droid2 - my desktop computer email client stopped receiving new emails. I can send email from my desktop email application (MacMail) but no new messages come in - only my cell DROID2 receives new emails ... what's up with that? I use K9 for 2 email accounts (secondary accounts) and the regular email app for 1 other (my primary account). None of these accounts are working anymore on my computer - only on the cell! :mad:
