It appeared in 2.5.11 according to my build environment. But there already was the option timeout: 30 before. So every connection was closed by default after 30 minutes if there was no activity. "imapidletimeout" uses the value of "timeout" as upper limit default as well. > But I've added it to the .conf anyway.

We had "dead" connections as well before imapidletimeout existed and I was able to get rid of them by activating keepalives to trigger the "timeout: 30" check.
