You can't include the \
after +myaccount/Sent \
in the separate config file. Or at least, the following works for me:
~/.muttrc
contains:
source ~/.mutt/mboxconf source ~/.mutt/bindings
And ~/.mutt/mboxconf
contains:
mailboxes +myaccount/INBOX \ +myaccount/Drafts \ +myaccount/Blah \ +myaccount/Sent
And ~/.mutt/bindings
contains:
macro index c "<change-folder>?<toggle-mailboxes>" "open a different folder" macro pager c "<change-folder>?<toggle-mailboxes>" "open a different folder"
But as soon as I add a \
after +myaccount/Sent
the macros no longer work.
