How to import existing emails

Use the pilerimport utility to import an EML message file, messages from an mbox file or emails from a directory containing EML format messages (1 message per file).

IMPORTANT! pilerimport doesn't change or delete the imported file, only reads it.

IMPORTANT! The pilerimport utility is setuid to the piler user, and to let it create some temporary files you have to cd to a directory where the piler user has write access.

Import a single EML file:

pilerimport -e message-from-jack.eml

Import a single EML file from STDIN:

pilerimport -e -

Import all messages from an mbox file:

pilerimport -m ~sj/201112.mbox

Import all messages from a directory having EML messages:

pilerimport -d ~/Maildir/new

Import messages from an IMAP server:

pilerimport -i <imap server> -u <username> -p  <password> [-x comma,separated,skiplist]

By default pilerimport will skip the Junk, Trash, Spam and Draft folders (= -x junk,trash,spam,draft). If you want to import emails from all imap folders (including junk, spam, #), then specify -x ''.

Import emails from a public folder:

pilerimport -i 1.2.3.4 -u joe -p secretpassword -f publicfoldername -a the.extra@email.address

To import all email except from the folder 'Draft' from imap server 1.2.3.4 using the account 'joe':

pilerimport -i 1.2.3.4 -u joe -p secretpassword -x draft

Import messages from a POP3 server:

pilerimport -K <imap server> -u <username> -p  <password>

Import with adding folder information

pilerimport -d /path/to/directory -f OLDEMAILS

Import with adding folder information using subdirectory names as subfolders

pilerimport -d /path/to/directory -f OLDEMAILS -R

How to import a PST file?

pilerimport can't read it, however you can extract the contents of the PST file with the readpst utility from the libpst package, then use pilerimport to import the required messages.

You may use the following command:

readpst -M -b /path/to/file.pst

Important! Make sure that the extracted emails have proper headers, eg. valid From: address (and not just <MAILER-DAEMON> for the sent items), To: address(es), Date: header, Message-ID: header, and even Received: lines. These are crucial for piler, and you will have problems without them.

How to use impersonation with Exchange?

add-mailboxpermission username -AccessRights FullAccess -user superuser
pilerimport -i mail.domain.com -u domain.com/superuser/username -p superpassword
remove-mailboxpermission username -AccessRights FullAccess -user superuser

Replace 'username' with your email user (no @domain necessary), 'superuser' with your import user, and 'superpassword' with your import user's password, and 'domain.com' with your domain.
