Catatan ini saya goreskan ketika melakukan migrasi mail server qmail ke zimbra mail server yang saat ini sedang booming.

Ketika kita melakukan migrasi mail server dan setiap user membaca email dengan POP3 maelalui email client, hal ini tidak menjadi masalah karena email setiap user sudah di download di komputer user masing – masing.

Tetapi ada kalanya ada user atau account email yang hanya boleh di baca melalui webmail karena mobilitas kerja yang menuntut membaca email di luar kantor

Nah konsep disini adalah migrasi dari email server yang satu ke email server yang lain yang mailboxny a masih tersimpan di server, menggunakan tools Imapsync yang scriptnya saya dapat wiki.zimbra.com.

Migrasi ini adalah migrasi mailbox per user, Sebelum menggunakan imapsync di perlukan softawre – software pendukung seperti Mail-IMAPClient-2.2.9, Digest-MD5-2.36, Date-Manip-5.54, Imapsync-1.255

Simulasi :

Server Qmail => host : 202.xx.xx.xx

user1 : yamin@domain1.com

password : xyz

Server Zimbra =>host : 202.xx.xx.xx

User2 : yamin@domain2.com

Pass : xyz

Berikut Scriptnya :

imapsync –buffersize 8192000 –nosyncacls –subscribe –syncinternaldates –host1 202.xx.xx.xx –user1 yamin@domain1.com –password1 xyz –ssl1 –port1 993 –host2 202.xx.xx.xx –user2 yamin@domain2.com –password2 xyz –ssl2 –port1 993 –noauthmd5

Bila berhasil maka setidaknya akan muncul log seperti di bawah ini :

$RCSfile: imapsync,v $ $Revision: 1.255 $ $Date: 2008/06/24 16:38:49 $
Here is a [linux] system (Linux mail2 2.6.22.5-31-default #1 SMP 2007/09/21 22:29:00 UTC i686)
with perl 5.8.8 and the module Mail::IMAPClient version used here is 2.2.9
Command line used :
