mailbox Sent {
auto = subscribe

}
说明：
# auto:
# Indicates whether the mailbox with this name is automatically created
# implicitly when it is first accessed. The user can also be automatically
# subscribed to the mailbox after creation. The following values are
# defined for this setting:
# 指示首次访问时是否隐式自动创建具有此名称的邮箱。
# 用户还可以在创建后自动订阅邮箱。为此设置定义了以下值：
#
# no - Never created automatically.(从不自动创建)
# create - Automatically created, but no automatic subscription.(自动创建但不自动订阅)
# subscribe - Automatically created and subscribed.(自动创建并订阅)
#
# special_use:
# A space-separated list of SPECIAL-USE flags (RFC 6154) to use for the
# mailbox. There are no validity checks, so you could specify anything
# you want in here, but it's not a good idea to use flags other than the
# standard ones specified in the RFC:
# 用于邮箱的专用标志（RFC 6154）的以空格分隔的列表。
# 没有有效性检查，所以你可以在这里指定任何你想要的东西，
# 但使用RFC中指定的标准标志之外的标志不是一个好主意。
#
# \All - This (virtual) mailbox presents all messages in the
# user's message store.
# \Archive - This mailbox is used to archive messages.(归档邮件)
# \Drafts - This mailbox is used to hold draft messages.(草稿邮件)
# \Flagged - This (virtual) mailbox presents all messages in the
# user's message store marked with the IMAP \Flagged flag.(被标记的邮件)
# \Important - This (virtual) mailbox presents all messages in the
# user's message store deemed important to user.(重要邮件)
# \Junk - This mailbox is where messages deemed to be junk mail
# are held.(垃圾邮件)
# \Sent - This mailbox is used to hold copies of messages that
# have been sent.(已发送邮件)
# \Trash - This mailbox is used to hold messages that have been
# deleted.(已删除邮件)
