Imapsync. IMAP migration

 

Migrating an IMAP account from one IMAP server to another [ 1 ] / Linux, command line: imapsync --host1 imap.this.com --user1 email@example.com --passfile1 /home/user/imap/passwordfile1 --ssl1 --host2 imap.another.com --user2 email@example.com --passfile2 /home/user/imap/passwordfile2 --ssl2 --skipsize --allowsizemismatch - There is a web site (example.com) and an email box (email@example.com) hosted at a web hosting company. The IMAP server: imap.this.com. The IMAP server supports SSL. - The example.com web site is to be transfered to another web hosting company. So is the email@example.com box with all its contents and keeping its folders structure. The IMAP server of another web hosting company: imap.another.com. The IMAP server supports SSL. 1. Set up an email box named email@example.com and a password to it on the server of the web hosting company the email@example.com mailbox is to be transfered to - from the previous web hosting company. 2. Create two text files in /home/user/imap/: passwordfile1 with the password for the mailbox on the first IMAP server and passwordfile2 with the password for the mailbox on the second IMAP server. 3. chmod 600 /home/user/imap/passwordfile1 4. chmod 600 /home/user/imap/passwordfile2 5. Install imapsync 6. Run imapsync Imapsync transfers a mailbox - keeping its folders structure - from imap.this.com to imap.another.com. SSL is used to enable encryption and passwords are saved to protected files (chmod 600). Migration between two email service boxes may happen to require to make use of more imapsync options [ 2 ]. Like transfering contents of one Gmail.com box to another demands to have "--port1" and "--port2" specified: imapsync --host1 imap.gmail.com --port1 993 --user1 email1@gmail.com --passfile1 /home/user/imap/passwordfile1 --ssl1 --host2 imap.gmail.com --port2 993 --user2 email2@gmail.com --passfile2 /home/user/imap/passwordfile2 --ssl2 --skipsize --allowsizemismatch [ 1 ] A simple and common case: contents of one email box are transfered to another, empty mailbox. But there can be more complicated ones like: Gmail to Google Apps Email Migration and Moving to Google Apps with imapsync.

Extract tar.bz2

 

Extracting tar.bz2 files in Linux, command line: tar jxvf file.tar.bz2 - j : filter the archive through bzip2 [ 1 ] - x : extract files from an archive - v : list the files processed - f : use archive file The command extracts the contents of a bzip2 compressed archive to the current directory. Tar creates an archive of one or several files. Then bzip2 is used to compress it. Or both processes are made at once by tar only, with corresponding options employed. The duality of nature - archived and then compressed - is reflected in the extension of the file ("tar.bz2") and requires two procedures to be performed while extracting: decompressing and unpacking. Hence both j (decompress it) and x (unpack it) in the command. [ 1 ] Sources for the option letters description: tar(1) - Linux man page and LinuxCommand.org
