Why emclient ver 6 and 7 doesn’t find some emails when using search function? example send address is email@example.com - if I’m looking by aaa it isn’t showing all emails send to firstname.lastname@example.org. The same if I type emclient.com - it doesn’t show all messages send to this addresses.
Try using * to separate the text you’re searching for. eM Client does not consider “@” as a separator.
