Horde_Imap_Client_Socket_Pop3 extends Horde_Imap_Client_Base
in package

An interface to a POP3 server using PHP functions.

It is an abstraction layer allowing POP3 commands to be used based on IMAP equivalents.

This driver implements the following POP3-related RFCs:

  - STD 53/RFC 1939: POP3 specification
  - RFC 2195: CRAM-MD5 authentication
  - RFC 2449: POP3 extension mechanism
  - RFC 2595/4616: PLAIN authentication
  - RFC 2831: DIGEST-MD5 SASL Authentication (obsoleted by RFC 6331)
  - RFC 3206: AUTH/SYS response codes
  - RFC 4616: AUTH=PLAIN
  - RFC 5034: POP3 SASL
  - RFC 5802: AUTH=SCRAM-SHA-1
  - RFC 6856: UTF8, LANG

                   does not support mod-sequences.

  - Horde_Imap_Client::STATUS_SYNCMODSEQ
    Return key: syncmodseq
    Return format: (integer) If caching, and the server supports the
                   CONDSTORE IMAP extension, this is the cached
                   mod-sequence value of the mailbox when it was opened
                   for the first time in this access. Will be null if
                   not caching, CONDSTORE not available, or the mailbox

  - Horde_Imap_Client::STATUS_SYNCFLAGUIDS
    Return key: syncflaguids

                   mailbox contained cached data when opened for the
                   first time in this access, this is the list of UIDs
                   in which flags have changed since STATUS_SYNCMODSEQ.

  - Horde_Imap_Client::STATUS_SYNCVANISHED

                   other cases, this value will be false.

  - Horde_Imap_Client::STATUS_FORCE_REFRESH
    Normally, the status information will be cached for a given
    mailbox. Since most PHP requests are generally less than a second,
    this is fine. However, if your script is long running, the status
    information may not be up-to-date. Specifying this flag will ensure
    that the server is always polled for the current mailbox status
    before results are returned. (since 2.14.0)

  - Horde_Imap_Client::STATUS_ALL (DEFAULT)
    Shortcut to return 'messages', 'recent', 'uidnext', 'uidvalidity',
