User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:188.8.131.52) Gecko/2008121622 Ubuntu/8.10 (intrepid) Firefox/3.0.5 Build Identifier: version 184.108.40.206 (20081125) I installed Thunderbird via Kubuntu 8.10 on a new system and shared an IMAP account. I have (rather: had!) a never-delete policy on my email account that enables (rather: enabled!) me to find all my communication and communication partners I had since 2003. A few days after installation I wondered why all emails are missing that date before November this year. Reproducible: Always Steps to Reproduce: 1. 2. 3.
OK, that got filed a bit too fast, I was not quite finished: Now I recognized that there is a setting in my account preferences that deletes all emails older than 20 (30, on another account) days. This setting definitely can't be set from me, I would never allow this. This is definitely an unwanted default setting. For me, it destroyed irrevocably all my email from the past 5 years.
I can't confirm this, the default setting in the account preferneces didn't have this pref set for me. Do you use an original mozilla.org build ?
