atomic or not - it would be better to apply a new field on a view non-atomic than see no messages at all in random mail clients what makes it really hard is that every random client is using other commands and i did not have any problem with thunderbird while roundcubemail stopped to list any message giving this who knows what mail client works currently or how broken is it since i can hardly test any client out there :-)
