I use Mutt Maildir for storage mails.
I created one mailbox like this Stack Exchange/. (whitespace between Stack and Exchange here)
procmailrc recipe:
:0
* From: .*Stack\ Exchange
Stack Exchange/
But upper recipe destination setting failed. after test and watch the log file.
I found procmail jumped through Exchange/, deliver email to Stack file, instead of Stack maildir folder, nor Stack Exchange/ maildir folder.
And I googled procmail settings, FAQ etc. not found relative problems.
So, does anybody knows how to escape whitespace here ?
