Is InMotion causing deletion of my local copies of e-mails?
I want to keep all of my deleted messages. In Mozilla Thunderbird, under "Account Settings> Server Settings> Message Storage," I have unchecked "Empty Trash on Exit." But only a week's worth of deleted messages are retained. The missing messages are not under "Archive." I am using an IMAP server through Inmotion. I did not have this problem with my previous provider, or another Inmotion account using a POP3 server and the same Thunderbird settings. The Thunderbird community says Inmotion accounts have caused Outlook deletions, so I want to know if this is a problem with Thunderbird as well.
