How to transfer my old email from my old hosting provider
Moving an email account (including old emails) from one cPanel server to another is pretty easy to do yourself if you have some knowledge of cPanel and FTP. If you don't feel comfortable doing it, we can always assist you. Open a support ticket if you need help.
Step 1: Create a new email account on the NEW SERVER with the same address and password
You can do this by going into the cPanel on the NEW SERVER and click on Email Accounts.
Step 2: Download the files off of the OLD SERVER
FTP onto the OLD SERVER and download the files needed. From the root directory, go to “mail/domain.com/emailAccount”. Here you will see a bunch of files. All you really need to copy are the new and cur directories.
If you have a lot of emails this could take a while.
Step 3: Transfer files to NEW SERVER
When the files are downloaded in step 2 place the new and cur directories in the “root/mail/domain.com/emailAccount” of the respective account on the NEW SERVER. The folder should already be created since you already created the account in step 1.
Go get some coffee. This step will take awhile as well.
Step 4: Reset Mail Quota
Now if you check the NEW SERVER you will see that your emails are transferred but your quota says 0/xxx MB. To update a wrong mail quota in cPanel: FTP to the OLD SERVER, open up the maildirsize file at “root/mail/domain.com/emailAccount” and copy all of the contents and paste them into the maildirsize file on the NEW SERVER.
You may have luck copying the maildirsize file on the OLD SERVER and pasting it on the NEW SERVER, however this did not work for me.
Step 5: Change DNS
If you followed all of the steps up to this point you should have all the files transferred, but you still need to point your DNS records to the NEW SERVER in order to have mail go there. When you update your records it could take up to 24 hours to take effect.
Step 6: Test
Finally, send a test email to the account. If that works send an email from the account. You’re done!
NOTE - This only works on hosting providers that use cPanel. If your old hosting provider does not use cPanel, you will have to contact them to transfer your email.
