Thunderbird has had hidden support (Maildir is disabled by default) for the Maildir mail storage format for several years, but Maildir is still not 100% ready for users. This article explains the format change and how to test Maildir starting in Thunderbird 38 (Maildir is not ready for testing prior to version 38).
- Backups are easier because the amount of data needed to be backed up is reduced to just those emails that have changed since the last backup.
- It is easier for anti-virus to scan emails in individual files, and infected mails can be removed without the loss of all the other mail in the folder, as often occurs today with anti-virus software which cannot handle multiple emails in one file.
This is a major change for Thunderbird because it changes the mail storage mechanism. The development team have spent a significant amount of time developing maildir.
However, due to a lack of time and testers before Thunderbird 38 was released, the actual underlying changes have not had the extensive manual testing that would normally occur for such a major change.
