Gmail gets IMAP. Fantastic I thought. Given that I consolidate several accounts inside Gmail as an additional backup service and presently have to manually synch them , this would make life much easier.
And then you read the small print courtesy of Webware
it’s worth noting that the IMAP support is one-way: You can use IMAP clients to read and send your Gmail. You cannot use the Gmail interface to access e-mail from non-Google IMAP servers or from Exchange. The only non-Google e-mail servers that Gmail can access are POP machines, and you don’t get any mailbox synchronization with that method.
