  #imap_max_line_length = 65536

  # clients to request it with CAPABILITY command, so it saves one round-trip.
  # Many clients however don't understand it and ask the CAPABILITY anyway.
  #login_greeting_capability = no

  # Workarounds for various client bugs:
  #   delay-newmail:
  #     Send EXISTS/RECENT new mail notifications only when replying to NOOP
  #     and CHECK commands. Some clients ignore them otherwise, for example
  #     OSX Mail. Outlook Express breaks more badly though, without this it
  #     may show user "Message no longer in server" errors. Note that OE6 still
  #     breaks even with this workaround if synchronization is set to
  #     "Headers Only".
  #   outlook-idle:
  #     Outlook and Outlook Express never abort IDLE command, so if no mail
  #     arrives in half a hour, Dovecot closes the connection. This is still
  #     fine, except Outlook doesn't connect back so you don't see if new mail
  #     arrives.
  #   netscape-eoh:
  #     Netscape 4.x breaks if message headers don't end with the empty "end of
  #     headers" line. Normally all messages have this, but setting this
  #     workaround makes sure that Netscape never breaks by adding the line if
  #     it doesn't exist. This is done only for FETCH BODY[HEADER.FIELDS..]
  #     commands. Note that RFC says this shouldn't be done.
  #   tb-extra-mailbox-sep:
  #     With mbox storage a mailbox can contain either mails or submailboxes,
  #     but not both. Thunderbird separates these two by forcing server to
  #     accept '/' suffix in mailbox names in subscriptions list.

## POP3 specific settings

  # from new/ to cur/, with mbox it doesn't write Status-header.
  #pop3_no_flag_updates = no

  # Support LAST command which exists in old POP3 specs, but has been removed
  # from new ones. Some clients still wish to use this though. Enabling this
  # makes RSET command clear all \Seen flags from messages.

  # POP3 UIDL format to use. You can use following variables:
  #
  #  %v - Mailbox UIDVALIDITY
  #  %u - Mail UID
  #  %m - MD5 sum of the mailbox headers in hex (mbox only)
  #  %f - filename (maildir only)
  #
  # If you want UIDL compatibility with other POP3 servers, use:
  #  UW's ipop3d         : %08Xv%08Xu
  #  Courier version 0   : %f
  #  Courier version 1   : %u
  #  Courier version 2   : %v-%u
  #  Cyrus (<= 2.1.3)    : %u
  #  Cyrus (>= 2.1.4)    : %v.%u
  #
  # Note that Outlook 2003 seems to have problems with %v.%u format which is
  # Dovecot's default, so if you're building a new server it would be a good
  # idea to change this. %08Xu%08Xv should be pretty fail-safe.
