Does anyone know an open source tool, which can export all e-mails from a provider like Google Mail, Hotmail, Yahoo or similar?
Obviously, one can do that with Thunderbird, but it’s cumbersome and I think it only works for a certain amount of e-mails. If you have more than 10,000 e-mails, then Thunderbird won’t help much, as far as I know.
When Gmail was shutting down Legacy Gmail I moved north of 82,000 emails from one account, 15k and 4k on two others and then between 60k, 20k, 20k and 20k on not-for-profits – all with Thunderbird. Yes, it will do it. Yes, its slow. I did it all those accounts plus a few other smaller accounts in TB on one computer. If there is another way (because I do not trust them not to do it again but I moved back because sadly the alternatives out there mostly sucked) it would be great!
Speed is not a problem for me. I just want as little manual involvement as possible. Ideally, I just wanna press a couple of buttons and then come back 8 hours later to see if it’s finished. I don’t want to babysit it for hours.
I actually used Thunderbird and it worked pretty well.
The key to success was the following tool.
It allows lots of possibilities of export.
I had to sort all mails inside the inbox by retrieval date, ascending, so it will start downloading the oldest mail possible and finish with the most recent one.
After hours of downloading and a couple of download interruptions, as the server was apparently getting tired, I just had to select all mails, right click, then choose one of the options provided by the extension linked above.
Yes. And even if it had one, I am sure it would take more time to do it this convoluted way. Doing it the way I described earlier is very convenient and easy. Not much to horse around, like people are used to on Linux, most of the time.
That said, this way does not solve the original problem in any way. The problem was getting out all e-mails from an account. I don’t want to transfer it to another account, because then I would still need to extract them from the other account.
This is a worse job of “solving” the issue, because you would need to do further manual processing. This is not an export. It’s more or less like POP3. However, exporting usually implies the choice of the format the content should be exported as. For example, with the solution I portrayed earlier, it is possible to export it to PDF, HTML, plain text with attachments or without, etc…
