I use Mail.app 1.3.9 (v610) under Panther 10.3.5 with two POP3 e-mail accounts. When I receive e-mail from these accounts, copies of the e-mail stay on the server for one account and not for the other account. I want e-mail to be erased from the server when I pick it up for both accounts. These e-mail accounts use the same e-mail server, where they are set up identically, other than the mailbox name. They are set up identically in Mail.app as well, except for the account name and e-mail address. In particular, they both have the "Remove copy from server after retrieving a message: Right away" option checked. I have even confirmed this by peeking in file ~/Library/Preferences/com.apple.mail.plist and seeing that it says <key>DeletionPolicy</key> <string>RightAway</string>for both accounts. To make sure "it heard me", I tried unchecking the "Remove copy..." setting, saving, quitting, launching, checking it, saving, quitting and launching again. The problem remains. Somehow the setting doesn't work for one account. I can manually click "Remove now" in Mail.app preferences, and the e-mail is removed from the e-mail server. But, for one out of two accounts, it does not remove e-mail automatically at the time it is received. Any ideas?
