After some investigation, I found out that the remote mailbox name had changed from "[Gmail]/All Mail" to "[Gmail]/ಎಲ್ಲಾ ಮೇಲ್". However, changing the name in my .fetchmailrc didn't fix the issue. The exact output I got when running fetchmail in verbose mode is given here:

Hello Chiraag,

you are right, fetchmail does not currently transcode mailbox names to
the modified UTF-7 format that IMAP requires for mailbox names per
RFC3501 chapter 5.1.3, <https://tools.ietf.org/html/rfc3501#page-19>

Does it work if you specify

folder "[Gmail]/&DI4MsgzNDLIMvg- &DK4MxwyyDM0-"

? (I hope my gnome-terminal and Thunderbird and clipboard haven't messed
up my copy and paste and that I haven't made a mistake translating the
mailbox name to modified UTF-7)

Regards,
