Core 9
with FreePascal 2.2.4)
IMAPCopy-Source
IMAPCopy is a small command line tool to copy messages for multiple
users from one imap server to another. I wrote the program to migrate
messages from a linux box to exchange but it works with other imap
implementations as well. The tool is designed for one time migrations,
it does not check if a mail already exists on the target server.
It is written in pascal and can be compiled with freepascal or delphi 3.
2009/07/18: Update
2006/04/20: Update
- Added a config directive to filter out unwanted flags (Thanks Ciprian).
Some Hints from Ciprian about the problem with the \Recent flag
If you do not specify a given list of flags to be copied thus resorting to "copy all flags" you are strongly advised to use DenyFlags for the "\Recent" flag. (This is included in the default config file) If the mailbox you are trying to copy has some messages marked by the server "\Recent" this flag can not be carried over (as per RFC). Not excluding "\Recent" may even result in imapcopy runs that fail for the first time but work for the next attempt(s).
2005/04/10: Update
- Fixed a memory leak in the folder list (Thanks Christiaan for reporting this).
2005/02/25: Update
- Applied patch from Christiaan den Besten to support skipping specified folders and to supress INBOX.INBOX. In case the INBOX.INBOX removement will cause some trouble, drop me a note and i will add a new switch for that.
- Compiled linux and win32 version with FreePascal 1.9.8 (debug symbols and -gl)
2004/11/04: Update
- parts of the last server response was added to the destination mail
2004/08/20: Update
- fixed cr/lf problem, imapcopy assumed that lines always end with cr/lf (thanks Ciprian for figuring out that bug)
2004/03/31: Update
- Errors reported for some servers after append command
- Added -X to copy all messages to INBOX
2003/09/13: Update
2003/09/13: Update
- A blank line at the end of ImapCopy.cfg is no longer needed
- Tabs are supported in ImapCopy.cfg
- A list of supported flags for the destination server can be set in config file
- -e to create empty folders are supported now
- Added option -0 to only copy the folder structure without copy any message
- Added option -s to subscribe all folders (while copying with or without -0)
- changed inet.pp to support RedHat 9 also
2003/07/15: Source Update, can now be compiled with FreePascal 1.0.10 and 1.1
2002/01/26: Update, Problems with Lotus Notes as Source Server
2001/10/08: Update, INBOX was created as INBOX.INBOX if source and destination-servers both supports NAMESPACE
2001/10/09: Update, INBOX.INBOX again if source has no NAMESPACE and destination has NAMESPACE

Date support in APPEND dosent seem to work. Notes sets wrong dates, i.e. "03-Aug-2001 10:37:14 +0200" is interpreted as "24-May-1945 00:00:00 +0000". Currently i dont know how to set the correct date using notes on linux as a destination. |

Currently all private folders and messages are copyed. Public and other users folders will be skipped. You can specify additional folders that will not be copied (with skipfolder in configfile or -S on commandline). You can also specify folders that will be copied (with copyfolder in configfile or -O on commandline).
Before starting a full copy you should do a copy to a testuser with
the commandline-option -1. This will copy only the first message from
each folder. After that you can verify that folders can be created and
messages can be copied in general.
Note: Some users reported problems regarding flags. With
some servers the flags from the source server are not compatible with
the supported flags on the destination server. If you have problems
copying mails, please try to enable the AllowFlags directive in the
config file.
... and drop me a note in case it works (or if it will not work)
