Infernal beeping!! [postfix/bash]
Whenever new mail arrives in my inbox, a beep occurs for each message. I used to think it was fetchmail, because I deliver mail to port 25 with it, but when sending mail to my local mailbox it still happens, which makes me think it's postfix or bash. I read about disabling the visible bell, but don't want to kill beeps for everything. just supress them for mail delivery.
