Email migration using imapsync

Email migration is tough job.   There are application that can do this but,  it will not include emails with attachments.

I found imapsync do the job for me.   How I did it?  Here’s how:

Install imapsync

# apt-get install imapsync

The syntax is:

# /usr/bin/imapsync \

—host1 imap.truc.org —user1 foo —passfile1 /etc/secret1 \

—host2 imap.trac.org —user2 bar —passfile2 /etc/secret2

This syntax will only migrate 1 email account from 1 domain to another. I created a script that will read the details from file and process the migration.

#!/bin/sh
while read v1 v3 v4 v5 v6
do echo”$v1″ > gmail.account
echo “$v2″ > gmail.passwd
echo “$v4″ > domain.account
echo “$v5″ > domain.passwd
echo “$v6″ > domain.log.account

# to test the script you have to add —dry
# Dry run

imapsync —host1 imap.gmail.com —ssl1 –authmech1 LOGIN —user1 $v1 —password1 $v2 —host2 mail.domain.com —ssl2 —authmech2 LOGIN —user2 $v4 —passfile2 $5 —skipsize —allowsizemismatch —dry > /home/root/imapsync/logs/$v6
done < migrate.account

This script will read the email account detail from migrate.account up to the last record. Lists of email accounts that you want to migrate.

email@gmail.com gmailpassword email@domain.com domainpassword email_log

To run the script:

You have to set the permission of the script

# chmod 744 email.migration

Create a log folder

# mkdir logs

Run the script

# ./email.migration

And of you go.   Now, monitor the migration in log folder
