sent mail notification popup display duration

[René J.V. Bertin]

Hi,

I'm pretty certain that the popup confirmations about my mail having been sent stay up much longer than they used to, and in some cases I actually have to cancel them myself.

I can't seem to find if and where that property can be configured, can it? FWIW, this is on a trusty old Plasma4 desktop with KDE PIM 4.13.3 .

Thanks,
René
