i have reset my mail from POP to IMAP but what i find now is that only some email in my MBP mailbox obeys rules set turn emails in certain accounts a certain colour. It looks like its those that i recieve in the daytime on my iPhone, so when i open my MBP in the evening and the mailboxes sync, those that have already been read dont seem to have the colour applied.
Any ideas why? An explantion of what its doing? or what i can do?
