Edit File: 20-pop3.conf
## ## POP3 specific settings ## # Don't try to set mails non-recent or seen with POP3 sessions. This is # mostly intended to reduce disk I/O. With maildir it doesn't move files # 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_enable_last = no # If mail has X-UIDL header, use it as the mail's UIDL. #pop3_reuse_xuidl = no # Allow only one POP3 session to run simultaneously for the same user. #pop3_lock_session = no # POP3 requires message sizes to be listed as if they had CR+LF linefeeds. # Many POP3 servers violate this by returning the sizes with LF linefeeds, # because it's faster to get. When this setting is enabled, Dovecot still # tries to do the right thing first, but if that requires opening the # message, it fallbacks to the easier (but incorrect) size. #pop3_fast_size_lookups = no # POP3 UIDL (unique mail identifier) format to use. You can use following # variables, along with the variable modifiers described in # doc/wiki/Variables.txt (e.g. %Uf for the filename in uppercase) # # %v - Mailbox's IMAP UIDVALIDITY # %u - Mail's IMAP UID # %m - MD5 sum of the mailbox headers in hex (mbox only) # %f - filename (maildir only) # %g - Mail's GUID # # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu # Courier : %f or %v-%u (both might be used simultaneosly) # Cyrus (<= 2.1.3) : %u # Cyrus (>= 2.1.4) : %v.%u # Dovecot v0.99.x : %v.%u # tpop3d : %Mf # # Note that Outlook 2003 seems to have problems with %v.%u format which was # 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. # #pop3_uidl_format = %08Xu%08Xv # Permanently save UIDLs sent to POP3 clients, so pop3_uidl_format changes # won't change those UIDLs. Currently this works only with Maildir. #pop3_save_uidl = no # What to do about duplicate UIDLs if they exist? # allow: Show duplicates to clients. # rename: Append a temporary -2, -3, etc. counter after the UIDL. #pop3_uidl_duplicates = allow # This option changes POP3 behavior so that it's not possible to actually # delete mails via POP3, only hide them from future POP3 sessions. The mails # will still be counted towards user's quota until actually deleted via IMAP. # Use e.g. "$POP3Deleted" as the value (it will be visible as IMAP keyword). # Make sure you can legally archive mails before enabling this setting. #pop3_deleted_flag = # POP3 logout format string: # %i - total number of bytes read from client # %o - total number of bytes sent to client # %t - number of TOP commands # %p - number of bytes sent to client as a result of TOP command # %r - number of RETR commands # %b - number of bytes sent to client as a result of RETR command # %d - number of deleted messages # %{deleted_bytes} - number of bytes in deleted messages # %m - number of messages (before deletion) # %s - mailbox size in bytes (before deletion) # %u - old/new UIDL hash. may help finding out if UIDLs changed unexpectedly #pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s # Workarounds for various client bugs: # outlook-no-nuls: # Outlook and Outlook Express hang if mails contain NUL characters. # This setting replaces them with 0x80 character. # oe-ns-eoh: # Outlook Express and Netscape Mail breaks if end of headers-line is # missing. This option simply sends it if it's missing. # The list is space-separated. #pop3_client_workarounds = protocol pop3 { # Space separated list of plugins to load (default is global mail_plugins). #mail_plugins = $mail_plugins # Maximum number of POP3 connections allowed for a user from each IP address. # NOTE: The username is compared case-sensitively. #mail_max_userip_connections = 10 }
