help?

it looks have installed ppa offers newer version of php (7.0.9) main repositories (7.0.8). ppa doesn't seem offer 7.0.9 version of php7.0-imap. apt tries install newest version of php7.0-imap it's got available, package main repos. depends on 7.0.8-0ubuntu0.16.04.3 package main repos, ppas 7.0.9-1+deb.sury.org~trusty+1 isn't compatible.

you can either disable ppa, if don't need php 7.0.9 instead of 7.0.8, or can ppa 7.0.9 includes php7.0-imap well.
