Since a few years I can't quit Mail.app instantly. The more folders I have entered during the usage, the more folder Mail.app tries to close before it quits. Each close operation takes 3-8 sec to complete, so quitting the whole program takes half a minute or so. How can I skip or make this closing procedure faster?
I use an own IMAP server for my emails.
Reindexig mails, recreating accounts, etc. does not work.
