filename in a way which will be interoperable with existing readers. So
the UID is placed in the filename of the messages in the local maildir
mailbox rather than the :info field.
.P
When synchronizing multiple mailboxes on the same IMAP server, it is not
possible to select different SSL options for each mailbox. Only the options
from the first mailbox are applied since the SSL session is reused.
