Migrate / Backup your mails to gmail / google apps.

Hi All...

Here are some worked examples on how to do the synchronization to google hosted email system.

Step 1.
 Create directory to where you can store password files.

Step 2.
Make a list of password files. (A password file is one with only the password stored in it)

Step 3.
Check the version of imap-sync using in your computer. The synchronization works only with versions above 1.261. If you are using debian / ubuntu use the below command to check the version.

apt-cache policy imapsync
imapsync:
Installed: 1.286+dfsg-3ubuntu1
Candidate: 1.286+dfsg-3ubuntu1

Step 4.
After the installation of imapsync go to the password created directory.

Step 5.
To synchronize the mail from any domain to gmail OR google hosted apps use the following command. (Make sure imap has been enabled in the Gmail account)

$ imapsync --host1 mail.domain.com --user1 source@domain.com --noauthmd5 --passfile1 /path/to/passwordfile --host2 imap.gmail.com --user2 destination@domain.com --passfile2 /path/to/passwordfile --port2 993 --ssl2 --folder 'INBOX' 'INBOX.Sent'

Step 6.
If the given credentials are correct, the command will look like the following.


with perl 5.10.1
Mail::IMAPClient  3.21
IO::Socket        1.31
IO::Socket::SSL
Digest::MD5       2.39
Digest::HMAC_MD5
Term::ReadKey     2.30
Date::Manip

/usr/bin/imapsync --host1 mail.domain.com --user1 source@domain.com --noauthmd5 --passfile1 passwordfile --host2 imap.gmail.com --user2 source@domain.com --passfile2 passwordfile --port2 993 --ssl2 --folder INBOX INBOX.Sent
Turned ON syncinternaldates, will set the internal dates (arrival dates) on host2 same as host1.

Will try to use LOGIN authentication on host1
