How to show original sent date about import-mailbox-to-gmail HOT 4 CLOSED

Hi,

As you can see in line 267, the script uses dateHeader as the internal date source. That means that the "received date" you'll see in Gmail is the date in the message's Date header.

Gmail API doesn't provide a way to specify a separate "received date", it can either be the date when the message was imported, or parsed from the Date header.

Even if using the dateHeader option, you might still see the import date as the message's "received date", if Gmail failed to parse the Date header during the import. Please check the message you're importing and see if the date is formatted correctly as per RFC822.

Ah, thank you so much for your suggestion. Actually I'm not a developer, so I'm trying to figure out how to do this formatting check, but it's a little bit hard and cofusing..

If you have an mbox file, it's just a text file, that you should be able to open with any text editor. Then, look for the affected message (i.e. a message where you saw the wrong date in Gmail), and take a look at the line starting with Date: at the top of that message.

You'd often see that there's no such line at all, or it's there but formatted incorrectly (for example, date as "16/8/2022" instead of "16 Aug 2022").

Thank you @eesheesh for your precious help. Yesterday I finally was able to make everything work, importing all the mbox files into the Gmail accounts. I'm not sure what happened, because I didn't modify anyone of the mbox files. But in the end it worked.
Thanks again for your support!
