splitmailbox

Simple tool to split your mailbox or maildir.

You can customize the directory, prefix, name and suffix of the output mailboxes using the headers of the messages stored in your mailbox. Prefix, name and suffix are expanded by str.format function.

Path of output mailboxes

Prefix, name and suffix are expanded by str.format function. The keyword arguments of the function are the header of the mail (see Python class email.message.Message), with some extensions:

• Date header is a datetime.datetime object

Examples

Split messages by year

splitmailbox --suffix '_{Date:%Y}' mail/mbox

Will create the mailboxes mail/mbox_2000, mail/mbox_2001, ...

Limitations

• Directory are not created at runtime (e.g. --prefix '{Date:%Y}/{Date:%m}')
