# IMAP, POP3 and NNTP

# Introduction

Warning

This extension is DEPRECATED and UNBUNDLED as of PHP 8.4.0.

These functions enable you to operate with the IMAP protocol, as well as the NNTP, POP3 and local mailbox access methods.

Be warned, however, that some IMAP functions will not work correctly with the POP protocol.

Warning

The IMAP extension is not thread-safe; it should not be used with ZTS builds.
