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
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 --user1 --noauthmd5 --passfile1 /path/to/passwordfile --host2 --user2 --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
Digest::MD5       2.39
Term::ReadKey     2.30
with perl 5.10.1Mail::IMAPClient  3.21IO::Socket        1.31IO::Socket::SSL   Digest::MD5       2.39Digest::HMAC_MD5 Term::ReadKey     2.30Date::Manip

/usr/bin/imapsync --host1 --user1 --noauthmd5 --passfile1 passwordfile --host2 --user2 --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
Will try to use LOGIN authentication on host2
