Importing Messages From IMAP to Gmail (Without Google's Tool)

I recently moved most of my email accounts into Google apps (effectively gmail), and wanted to move all of my mail history across too (to make use of all that searchy goodness).

Unfortunately, Google Deprecated their Imap migration tool and recommend you use their Exchange tool instead (pah!). But there’s an easier way! Just use Thunderbird (or your imap email client of choice).

I simply setup two accounts in Thunderbird:
  • One imap account pointing at my old provider
  • Another IMAP pointing at Gmail (go to account settings in Gmail, and ensure IMAP is enabled first).
Then I simply dragged all my mail from one account to the other in Thunderbird. It’s slow, but seems to have worked fine.
