Yes. 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.

I currently don't remember if imapd ignores unknown options or fails on startup.

But maybe the better option is to use
tcp_keepalive: yes
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.
