Oh crap. Gmail is deprecating support for picking up mail from a remote server using POP3 polling in January 😭 Given that I switched to this mode due to reliability problems with direct delivery via mail forwarding, this really sucks...
@jmason you still have imap ?
@R1Rail as I understand it, that isn't usable as a means to "import" mails into the main Gmail store from an external mailbox
@jmason Ah ok, I undertood the other way, reading email in gmail.
