         Imapsync tips for various imap server softwares.
=======================================================================



=======================================================================
Q. From or to Zimbra

R. Read the FAQ.Zimbra.txt 
   https://imapsync.lamiral.info/FAQ.d/FAQ.Zimbra.txt

=======================================================================
Q. From or to HMailServer version 4.4.1.

R. You have to add prefix and separator manually because  4.4.1 doesn't
honor the NAMESPACE imap command.

Example for host1:

imapsync ... \
         --prefix1 "" --sep1 .

No specific option for HMailServer 5.3.3 since NAMESPACE is supported.

Maybe --subscribe_all will help you to see all migrated folders.


=======================================================================
Q. from Microsoft's Exchange 2007 to Google Apps for your Domain 
   (GAFYD)

R. Take a look at:

=======================================================================
Q. Migrating from or to Parallels Plex Server

R. It depends on the OS

Parallells Plesk Panel for Windows requires --sep2 / --prefix2 ""
Parallells Plesk Panel for Linux works with default parameters.

=======================================================================
Q. I'm migrating from WU to Cyrus, and the mail folders are under
   /home/user/mail but the tool copies everything in /home/user, how
   can i avoid that?

Two solutions:

R. Use
   imapsync ... --include '^mail'

R. or (better)
   imapsync ... --subscribed --subscribe


=======================================================================
Q. I'm migrating from WU to Cyrus, and the mail folders are under
   /home/user/mail directory.  When imapsync creates the folders in
   the new cyrus imap server, it makes a folder "mail" and below that
   folder puts all the mail folders the user have in /home/user/mail,
   i would like to have all those folders directly under INBOX.

R. Use 
   imapsync ... --regextrans2 's/^mail/INBOX/' --dry
   look at the simulation and if all transformations seem
   good then remove the --dry option.


=======================================================================
Q. Migrating from Groupwise to Cyrus

R. By Jamie Neil:

I eventually managed to get the mail to migrate without errors using the 
following options:

--maxage 3650
  - some messages just don't seem to want to transfer and produce the 
    perl errors I mentioned before. This prevents the errors, but the
    bad messages don't transfer.

Even though the mail migrated OK, there are a couple of gotchas with 
Groupwise IMAP:

1) Some of the GW folders are not real folders and are not available
to IMAP, the main problem one being "Sent Items". I could find no way
of coping the contents of these folders. The nearest I got was to
create a "real" folder and copy/move the sent items into it, but
imapsync still didn't see the messages (I think because there is
something funny about the reported dates/sizes).

It think this problem has been rectified in GW6.5.

2) Version 6.0.1 of the Groupwise Internet Connector sucks. I was 
getting server aborts when I pushed it a bit hard! I eventually had to
upgrade to 6.0.4 which seems to be a lot more stable.

=======================================================================
Q. Migrating from iPlanet Messaging Server
5.2 Patch 2 (built Jul 14 2004)) to Groupwise 7.0
I encounter many errors like this:
"Error trying to append string: 17847 BAD APPEND"

R. GroupWise 7 seems buggy. Apply GroupWise 7 support pack 1


=======================================================================
Q. Migrating from or to David Tobit

R. See FAQ.David_Tobit.txt
   https://imapsync.lamiral.info/FAQ.d/FAQ.David_Tobit.txt

=======================================================================

Q. I need to migrate 1250 mailboxes, passwords are in a MySQL Database.
Can you tell me if your script suits my needs?

R. Mailboxes must exist before running imapsync.
You have to extract users logins and passwords in a csv file.
See the "HUGE MIGRATION" section in the README file.


======================================================================
Q: From MailEnable 1.75
R: --sep1 "/" --prefix1 ""

Q: From MailEnable 2.2
R: --sep1 "." --prefix1 ""

Q: To MailEnable
R: --sep2 / --prefix2 "" --addheader --messageidnodomain --syncflagsaftercopy

======================================================================
Q. From GMX IMAP4 StreamProxy
R. Use:
   --prefix1 INBOX and --sep1 .

======================================================================
Q. From Courier to Archiveopteryx
R. You can read http://www.archiveopteryx.org/migration/imapsync
   Default values might be fine now with latest imapsync.

======================================================================
Q. To Sun Java(tm) System Messaging Server 6.2-7.05
Q. To Communigate Pro - Solaris version

R. See and run patches/imapsync_1.267_jari


======================================================================
Q. From Softalk Workgroup Mail 7.6.4 

R. Old Softalk releases don't support the IMAP SEARCH command.
   Here are the options to get it working.

imapsync ... --sep1 '.' --prefix1 '' \
             --noabletosearch1  --nocheckmessageexists --addheader

(Thanks to Andrew Tucker)

======================================================================
Q. From or to QQMail IMAP4Server

R. imapsync ... --noabletosearch1

======================================================================
Q. From FirstClass to XXX
   http://www.firstclass.com/

R. Migrating from FirstClass is not easy because FirstClass, strangely, 
   does not show all messages via IMAP. To make it show all messages,
   a trick, painful to follow by hand, is moving emails 
   out and back in, for each folder. May be it can be done by a script.

  FirstClass releases prior to release 12 do not shows the "Sent" 
  folder in IMAP but FirstClass release 12 shows it.
  I advice you to upgrade to FirstClass release 12 before leaving it
  with imapsync or another imap tool.

Here is a command line used to migrate from FirtClass release 12:

  imapsync ... \
    --tmpdir /var/tmp --usecache \
    --useheader Message-ID \
    --idatefromheader \
    --addheader \
    --regextrans2 "s,(/|^) +,\$1,g" --regextrans2 "s, +(/|$),\$1,g" \
    --regextrans2 "s/[\^]/_/g"       \
    --regextrans2 "s/['\"\\\\]/_/g"  \
    --regextrans2 "s,&AC8-,-,g" \
    --regextrans2 "s,&APg-,oe,g" 

On Windows:
  imapsync.exe ... ^
    --automap ^
    --usecache ^
    --useheader Message-ID ^
    --idatefromheader ^
    --addheader ^
    --regextrans2 "s,(/|^) +,$1,g" ^
    --regextrans2 "s, +(/|$),$1,g" ^
    --regextrans2 "s/[\^]/_/g" ^
    --regextrans2 "s/['\\]/_/g" ^
    --regextrans2 "s,^&AC8-,-,g"  ^
    --regextrans2 "s,^&APg-,oe,g"


Special thanks to Kristian Wind and Joey Alexander for helping me
writing this FAQ item.

======================================================================
Q. From XXX to FTGate

R. Do NOT use --usecache since new UIDs are not given by FTGate and also
   badly guessed by imapsync. UIDEXPUNGE does not work so use also
   --expunge2 when using --delete2
  
  imapsync ... \
     --sep2 / --prefix2 "" \
     --useheader Message-Id \
