# If using the alternate IMAP namespace, the prefix for the other

# The  minimum  value  is  30,  the default.

#timeout: 30

# The interval (in seconds) for polling the mailbox for changes while
# running the IDLE command.  This option is used when idled can not be

# less liberal policy, it needs to change this parameter accordingly.

#postuser: <none>

# If enabled at compile time, this specifies a URL to reply when
