How to download all mail in Claws-mail
With Claws-mail, I want to be able to read all my mail even if offline, but the only way I know to download mail contents is by manually selecting it in the mail list. Additionally, navigating feels a bit sluggish because, as the manual says:
When using IMAP your folder list and your emails are all kept on a central server. This slows down navigation a little as each mail is downloaded on demand (...)
How can I download all my mail at once?
I inspected the preferences and preferences for current account under the configuration menu, but found nothing appropriate.
Message > receive > get from current account retrieves the headers of new messages in order to populate the inbox (or any other) folder, but message contents are not downloaded that way — just like Claws-mail does at initialization.
A solution would be to individually select each of the available mail when online, but of course it's not practical.
