Status: VERIFIED DUPLICATE of bug 58308

(Thunderbird :: General, enhancement)

I think mail folders format should be maildir format rather then mbox, because
it would be faster when looking into a folder with thousands of messages. And it
would be easier do fix any problem with a bad email, by deleting one email
message file, rather than search a big email file for the content for that email
message.

Reproducible: Always
Steps to Reproduce:
1. Have many emails on one email folder
2. Selected that folder
3. 

Actual Results:  
Watch the machine to be processing a large file to display the messages headers,
and after it, to open each message.

Expected Results:  
Opening the folder should be faster if the messages are separated into diferente
files, like maildir format style.

verifying the dup - but be aware that the reasons you give for using maildir are
not really valid - opening a message in a large folder just does a file system
seek to the offset of the message in the file, which is almost as fast as
opening a stand-alone file, and deleting a message in a large mailbox is just a
matter of updating a byte in the message; that will probably be faster than
deleting a file from the file system.
