POP 3 client is a PHP class that allows you to access mail boxes using the POP3 protocol. It provides a stream wrapper class for retrieving messages like files using the PHP fopen function, establishes secure connections using TLS, accesses servers using normal and APOP login methods, supports authentication mechanisms such as PLAIN, LOGIN, CRAM-MD5, NTLM (Windows or Linux/Unix via Samba) via the PHP SASL library, and supports listing of message sizes, retrieval of a message at once, separating the headers from the body, retrieving a message in small chunks to not exceed the available memory, and deleting messages.
This is a PHP class that attempts to validate a given e-mail address at three levels: matching the address against a RFC compliant regular expression, verifing the existence of the destination SMTP server by verifying the respective DNS MX record, and connecting to that server to see if the given address is accepted as a valid recipient. The class also features a debugging output option that lets you see the remote SMTP server connection and data exchange dialog to see the real cause why an apparently valid address may not be accepting messages.
