All of a sudden Thunderbird cut off my emails before a certain date. A couple of weeks ago I noticed that my older inbox emails were gone. Then today I noticed again that the emails before April 24th are gone. Is there some kind of setting that I accidentally reset as far as how long to keep emails? I went to my provider email site and had a little trouble finding my older emails but I thought I had it fixed. It shouldn't matter because I have seem to have lost emails that have already been downloaded on my computer. Thanks!
