Gmail labels.list failed with 429 (rateLimitExceeded): User-rate limit exceeded.

[Node815]

I have three personal accounts connected and it is pretty much blocking me from using Gmail. The app is set to "In Production" in Google cloud console.

Is there a solution for this?

[karatektus]

You have three personal gmail accounts? or three accounts and one of them is gmail?

I've pushed quite a few changes to fix this but have only ever tested it with one gmail account.
This is pretty much just an issue for initial imports. Are you using the app with this gmail account somewhere else too? plMail assumes it has the whole API limit for itself.

[Node815]

Three seperate accounts yes. It's during the first initial sync where it seems to be getting the errors.
Additionally, I have hundreds of thousands of errors like this (From one message, the full error text).

I wanted to included the full message to help with any diagnostic you may want to do.

Thanks for the full trace, it pointed straight at the cause. This is a bug, not your setup.

With more than one Gmail account connected, mail that one account forwards to another (or that both receive) still says Delivered-To: the first account. plMail then treated it as a copy belonging to the first account and merged it into that account's message. The merge overwrote the first account's Gmail id with the second mailbox's. The first account then imported the message again. The next batch that touched it tried to give one id to two rows, which is the uniq_message_gmail_id_account error you saw. The whole batch then failed and was fetched from Gmail again on every retry, and that is what used up the quota and led to the 429s. The merge was built for Gmail plus an IMAP account (Gmailify), and I had only ever tested it with one Gmail account.

The fix is in #196: a message another Gmail account already holds is now left with that account, and the import counts it as done instead of fetching it again. Once it's merged, the main image has it, and it'll be in the next release.

One caveat: messages that were already affected before the update may show up twice.

Thank you so much for fixing this!
