.bdx files

Hi

We're having some space issues with our mail server and in looking into
the mail directories on the server I'm seeing something I don't understand.

We use mailbox format MailDirMailBox. So, in my mail directory there is
a subdirectory for each folder I have in my mailbox. In some account
directories in addition to the sub-directory for each folder, there is a
file called folder_name.bdx that is pretty large. However, the
time-stamp on the file is over a year ago (probably about the time we
converted to the MailDirMailBox format.

Is this just an artifact left over from before the conversion, or is it
still used with our current mailbox format?

please take a look at this link:

http://www.communigate.com/cgatepro/Mailboxes.html#Formats

It says:

"To improve TextMailbox opening speed, the CommuniGate Pro can maintain
a Mailbox index (.bdx) file alongside the TextMailbox Mailbox file. If
the index file exists, the Server reads it instead of parsing the entire
Mailbox file. CommuniGate Pro automatically creates an index file when
it the Mailbox file size exceeds the specified limit. The Server removes
the index file if the Mailbox becomes smaller than that limit.
The Index file is created when any message in the Mailbox is modified or
deleted. If new messages have been added to the Mailbox, but the Mailbox
has not been opened, or it has been only read without any flag
modification, the Index file may not be created."

So the .bdx files are index files of the mbox format and you may delete
them if you use maildir now.

Kind regards,

Oliver Koch
