How to IMPORT this blocked attachments from gmail to another gmail?

[kingston896]

By enabling POP feature, I successfully imported almost all gmail inbox into new gmail inbox except 391 mails with

((has:attachment OR has:drive).dll)
Due to gmail blocked this .dll attachments, how to import leftover " .dll " files also to my new gmail inbox?

I know that enabling IMAP will help me. But I am new to IMAP thing in gmail.

The attachments are in fact .dll files? Google may be trying to protect your email. Not sure how to get past that one if that's the case. Are you using Thunderbird?

You might want to check out Protonmail. Read their FAQs and what not. You can set it up with Thunderbird, but you have to pay for their bridge which is about $5/month. The Android App has been pretty decent on my Moto G5 play.

It says on the google website:

Gmail can't import emails that are 150 MB or bigger, including any attachments.
