Unwanted dropdown arrow next to email address in Apple Mail
In Apple Mail, how do I get rid of this little dropdown arrow next to the email address? It's annoying because the dropdown contains all the folders within (sent, junk, etc.) which are also i the column below. So if I get a "junk" email , it show that I have something in my inbox for this account. The other inbox accounts down't have this little arrow.
