It seems that Mozilla has a 2GB (31 bit) limitation for the maximum file size of mail files (confirmed under Windows2000, NTFS filesystem). It seems that mail files can not grow larger then 2 GByte. Since a while my inbox is larger then 2GB and I am used to synchronize my email to read email offline. Reproducible: Always Steps to Reproduce: 1. 2. 3. Actual Results: The Inbox got unreadable after approching the 2GB filesize barriere. I tried everything to get Mozilla Mail working again. I removed the .msf Files to rebuilt the database, removed the INBOX and .msf file, etc. Result: INBOX got unreadable if getting larger then 2GB. The mail data is *completly* lost. Expected Results: Implementing 64-bit filepointers and fileaccess when runnig on an appropriate operating and file system.
A work around is to compact folder every time you delete a mail, and you will go under a 2 Gb mailbox :)
