imapsync --host1 x.x.x.x --host2 y.y.y.y --user1 usr1 --user2 test --password1 usrPass1 --authuser2
admin@test.domain --password2 adminPass --port2 7143
I know I need the --prefix2 and some others, but I'm just using this to test authentication before actually moving data.
Also, I amusing the admin password and I've tried the --authuser2 with the @test.domain and without it.
Thanks!
