Halo jumpa lagi sahabat sekolahlinux, kali ini saya akan membahas tentang bagaimana sih caranya migrasi email dari 1 email ke email lainnya, tentu ini sangat bermanfaat bagi sysadmin yang sedang mendapatkan tugas migrasi server tapi mail servernya beda engine, nah cara ini akan memudahkan anda, oke langsung saja ikuti cara ini, dan cara ini sudah saya coba di server kantor yang kebetulan berbeda engine mailnya 😀 hehe..

install dulu repo yang kita butuhkan

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

jika sudah install aplikasi imapsyncnya dengan perintah dibawah

yum install imapsync

untuk petunjuk anda bisa menggunakan man ataupun perintah help seperti dibawah ini

[root@akbar ~]# imapsync --help

usage: /usr/bin/imapsync [options]

Several options are mandatory.

--dry                  : Makes imapsync doing nothing, just print what would
                         be done without --dry.

--host1       <string> : Source or "from" imap server. Mandatory.
--port1       <int>    : Port to connect on host1. Default is 143.
--user1       <string> : User to login on host1. Mandatory.
--showpasswords        : Shows passwords on output instead of "MASKED".
                         Useful to restart a complete run by just reading a log.
--password1   <string> : Password for the user1.
--host2       <string> : "destination" imap server. Mandatory.
--port2       <int>    : Port to connect on host2. Default is 143.
--user2       <string> : User to login on host2. Mandatory.
--password2   <string> : Password for the user2.

--passfile1   <string> : Password file for the user1. It must contain the
                         password on the first line. This option avoids to show
                         the password on the command line like --password1 does.
--passfile2   <string> : Password file for the user2. Contains the password.
--domain1     <string> : Domain on host1 (NTLM authentication).
--domain2     <string> : Domain on host2 (NTLM authentication).
--authuser1   <string> : User to auth with on host1 (admin user).
                         Avoid using --authmech1 SOMETHING with --authuser1.
--authuser2   <string> : User to auth with on host2 (admin user).
--proxyauth1           : Use proxyauth on host1. Requires --authuser1.
                         Required by Sun/iPlanet/Netscape IMAP servers to
                         be able to use an administrative user.
--proxyauth2           : Use proxyauth on host2. Requires --authuser2.
                         Required by Sun/iPlanet/Netscape IMAP servers to
                         be able to use an administrative user

--authmd51             : Use MD5 authentification for host1.
--authmd52             : Use MD5 authentification for host2.
--authmech1   <string> : Auth mechanism to use with host1:
                         PLAIN, LOGIN, CRAM-MD5 etc. Use UPPERCASE.
--authmech2   <string> : Auth mechanism to use with host2. See --authmech1
--ssl1                 : Use an SSL connection on host1.
--ssl2                 : Use an SSL connection on host2.
--tls1                 : Use an TLS connection on host1.
--tls2                 : Use an TLS connection on host2.
--timeout    <int>     : Connections timeout in seconds. Default is 120.
                         0 means no timeout.

--folder      <string> : Sync this folder.
--folder      <string> : and this one, etc.
--folderrec   <string> : Sync this folder recursively.
--folderrec   <string> : and this one, etc.

--folderfirst <string> : Sync this folder first. --folderfirst "Work"
--folderfirst <string> : then this one, etc.
--folderlast  <string> : Sync this folder last. --folderlast "[Gmail]/All Mail"
--folderlast  <string> : then this one, etc.

--include     <regex>  : Sync folders matching this regular expression
                         Blancs like in "foo bar" have to be written "foo bar"
--include     <regex>  : or this one, etc.
                         in case both --include --exclude options are
                         use, include is done before.
--exclude     <regex>  : Skips folders matching this regular expression
                         Several folders to avoid:
			  --exclude 'fold1|fold2|f3' skips fold1, fold2 and f3.
--exclude     <regex>  : or this one, etc.
--regextrans2 <regex>  : Apply the whole regex to each destination folders.
--regextrans2 <regex>  : and this one. etc.
                         When you play with the --regextrans2 option, first
                         add also the safe options --dry --justfolders
                         Then, when happy, remove --dry, remove --justfolders.
                         Have in mind that --regextrans2 is applied after prefix
                         and separator inversion.

--tmpdir      <string> : Where to store temporary files and subdirectories.
                         Will be created if it doesn't exist.
			 Default is system specific, Unix is /tmp but
                         it's often small and deleted at reboot.
                         --tmpdir /var/tmp should be better.
--pidfile     <string> : The file where imapsync pid is written.
--pidfilelocking       : Abort if pidfile already exists. Usefull to avoid
                         concurrent transfers on the same mailbox.

--prefix1     <string> : Remove prefix to all destination folders
                         (usually INBOX. or INBOX/ or an empty string "")
                         you have to use --prefix1 if host1 imap server
                         does not have NAMESPACE capability, all other
                         cases are bad.
--prefix2     <string> : Add prefix to all host2 folders. See --prefix1
--sep1        <string> : Host1 separator in case NAMESPACE is not supported.
--sep2        <string> : Host2 separator in case NAMESPACE is not supported.

--disarmreadreceipts   : Disarms read receipts (host2 Exchange issue)
--regexmess   <regex>  : Apply the whole regex to each message before transfer.
                         Example: 's/00/ /g' # to replace null by space.
--regexmess   <regex>  : and this one.
--regexmess   <regex>  : and this one, etc.
--regexflag   <regex>  : Apply the whole regex to each flags list.
                         Example: 's/"Junk"//g' # to remove "Junk" flag.
--regexflag   <regex>  : and this one, etc.

--delete               : Deletes messages on host1 server after a successful
                         transfer. Option --delete has the following behavior:
                         it marks messages as deleted with the IMAP flag
                         Deleted, then messages are really deleted with an
                         EXPUNGE IMAP command.
--delete2              : Delete messages in host2 that are not in
                         host1 server. Useful for backup or pre-sync.
--delete2duplicates    : Delete messages in host2 that are duplicates.
                         Works only without --useuid since duplicates are
                         detected with header part of each message.
--delete2folders       : Delete folders in host2 that are not in host1 server.
                         For safety, first try it like this (it is safe):
			 --delete2folders --dry --justfolders --nofoldersizes
--delete2foldersonly   <regex>: Deleted only folders matching regex.
                         Example: --delete2foldersonly "/^Junk$|^INBOX.Junk$/"
--delete2foldersbutnot <regex>: Do not delete folders matching regex.
                         Example: --delete2foldersbutnot "/Tasks$|Contacts$|Foo$/"
--noexpunge            : Do not expunge messages on host1.
                         Expunge really deletes messages marked deleted.
                         Expunge is made at the beginning, on host1 only.
                         Newly transferred messages are also expunged if
			 option --delete is given.
                         No expunge is done on host2 account (unless --expunge2)
--expunge1             : Expunge messages on host1 after messages transfer.
--expunge2             : Expunge messages on host2 after messages transfer.
--uidexpunge2          : uidexpunge messages on the host2 account
                         that are not on the host1 account, requires --delete2

--syncinternaldates    : Sets the internal dates on host2 same as host1.
                         Turned on by default. Internal date is the date
			 a message arrived on a host (mtime).
--idatefromheader      : Sets the internal dates on host2 same as the
                         "Date:" headers.

--maxsize     <int>    : Skip messages larger  (or equal) than <int> bytes
--minsize     <int>    : Skip messages smaller (or equal) than <int> bytes
--maxage      <int>    : Skip messages older than <int> days.
                         final stats (skipped) don't count older messages
			 see also --minage
--minage      <int>    : Skip messages newer than <int> days.
                         final stats (skipped) don't count newer messages
                         You can do (+ are the messages selected):
                         past|----maxage+++++++++++++++>now
                         past|+++++++++++++++minage---->now
                         past|----maxage+++++minage---->now (intersection)
                         past|++++minage-----maxage++++>now (union)

--search      <string> : Selects only messages returned by this IMAP SEARCH
                         command. Applied on both sides.
--search1     <string> : Same as --search for selecting host1 messages only.
--search2     <string> : Same as --search for selecting host2 messages only.
                         --search CRIT equals --search1 CRIT --search2 CRIT

--exitwhenover   <int> : Stop syncing when total bytes transferred reached.
                         Gmail per day allows 2500000000 down 500000000 upload.

--maxlinelength <int>  : skip messages with a line length longer than <int> bytes.
                         RFC 2822 says it must be no more than 1000 bytes.

--useheader   <string> : Use this header to compare messages on both sides.
                         Ex: Message-ID or Subject or Date.
--useheader   <string>   and this one, etc.

--subscribed           : Transfers subscribed folders.
--subscribe            : Subscribe to the folders transferred on the
                         host2 that are subscribed on host1. On by default.
--subscribe_all        : Subscribe to the folders transferred on the
                         host2 even if they are not subscribed on host1.

--nofoldersizes        : Do not calculate the size of each folder in bytes
                         and message counts. Default is to calculate them.
--nofoldersizesatend   : Do not calculate the size of each folder in bytes
                         and message counts at the end. Default is on.
--justfoldersizes      : Exit after having printed the folder sizes.

--syncacls             : Synchronises acls (Access Control Lists).
--nosyncacls           : Does not synchronize acls. This is the default.
                         Acls in IMAP are not standardized, be careful.

--usecache             : Use cache to speedup.
--nousecache           : Do not use cache. Caveat: --useuid --nousecache creates
                         duplicates on multiple runs.
--useuid               : Use uid instead of header as a criterium to recognize
                         messages. Option --usecache is then implied unless
                         --nousecache is used.

--debug                : Debug mode.
--debugcontent         : Debug content of the messages transfered.

--releasecheck         : Check for new imapsync release (a http request).
--justconnect          : Just connect to both servers and print useful
                         information. Need only --host1 and --host2 options.
--justlogin            : Just login to both host1 and host2 with users
                         credentials, then exit.
--justfolders          : Do only things about folders (ignore messages).

--help                 : print this help.

Example: to synchronize imap account "foo" on "imap.truc.org"
                    to  imap account "bar" on "imap.trac.org"
                    with foo password "secret1"
                    and  bar password "secret2"

[root@akbar ~]#

yap sampai sini selesai sudah :D, jika gagal atau failed karena authentication default dari imapsync menggunakan tipe CRAM-MD5, jado untuk merubah defaultnya bisa dengan menambahkan metode ini

imapsync
> --host1 mail.domain1.com --user1 akbar@domain1.com --password1 J4gt3k --authmech1 <string>
> --host2 mail.domain2.com --user2 akbar@domain2.com --password2 J4gt3kn0 --authmech1 <string>

pada bagian <string> ganti dengan jenis enkripsi yang digunakan oleh mail server masing-masing tujuan dan jenis-jenisnya bisa kita lihat di comman imapsync –help

seharusnya email yang berada di server1 dengan user akbar@domain1.com sudah ada juga di server2 dengan user akbar@domain2.com

nah berikut ini script imapsync yang digunakan untuk koneksi server yang menggunakan IMAPS atau SSL dan tipe enkripsinya adalah LOGIN, contoh dibawah saya terapkan dari server exchange server ke cpanel/exim

imapsync
--host1 server1.sekolahlinux.com --user1 akbar@sekolahlinux.com --password1 'pa$$word1234' --authmech1 LOGIN --ssl1
--host2 server2.sekolahlinux.com --user2 akbar@sekolahlinux.com --password2 'pa$$word1234' --authmech1 LOGIN

Catatan: jika passwordnya menggunakan symbol juga maka harus menggunakan kutip satu agar bisa terbaca sebagai password oleh imapsync

sekian dari saya semoga bermanfaat 😀
