A few days ago I’ve mentioned that I have a problem with some of my email accounts. Â The thing was that I have a few mailboxes, and all of them forward all incoming messages to a single account that I use for everything. Â Some of the accounts forward emails using Gmai’s forwarder, some forward emails using a filter, and some mailboxes are checked for email via POP-3. Â That’s not because I like variety, but because all these accounts were created at different times, back when Gmail wasn’t as full featured as it is now.
Anyways. Â I realized that one of the accounts stopped forwarding the emails. Â I logged into it, and found that there were thousands of messages waiting for reply. Â None of these messages made it through the forwarder. Â The mailbox is also quite old, and has plenty of email history – most of which I already had in my central mailbox.
I tried to create a new filter so that I could only forward the ones that didn’t make, but that didn’t work. Â I played around with filters, IMAP access, and a few third-party scripts, but nothing was giving the result that I wanted. Â The only option left was POP-3. Â So I went for it.
The thing with POP-3 access in Gmail is that when you enable it, you have to choose for which messages – either only the new ones from this point, or for all of them. Â I had to go for the “all of them”.
The mailbox in question contains a history of 50,000 conversations. Â I cleaned up a bit, so just before the POP-3 pull started, I had around 35,000 conversations. Â Gmail’s POP-3 mail check works interestingly. Â It fetches a maximum of 200 messages per session. Â And it takes a few minutes’ break between sessions. Â It took just a bit over 48 hours to import all my messages to another account via POP-3!
Gladly, most of them were not duplicated. Â Gmail was smart enough to know which messages I already had and which I didn’t. Â And the ones that I didn’t went through the filtering process in the central mailbox, as they should. Â So after about 2 days of waiting, I’ve ended up with a couple of thousands of new messages. Â Sorted through them in a matter of an hour (thank you Gmail team for keyboard shortcuts!), and now I am up to speed again.
Thinking over this experience, I will probably go through the settings of all my other accounts and make sure that I am using POP-3 rather than filters or forwarders. Â Somehow I think it is a little bit more reliable.
