Examples of POP3Client

gov.iowa.ite.mail.POP3Client

Retrieves mail and attachments from a POP3 server, using the specified parameters. Params used are as follows:

Param Name	Default	Definition
host	(none)	Host name or IP address of the server to be contacted.
username	(none)	User ID on the server.
password	(none)	Password that goes with username on the server.
provider	"pop3"	The type of mail server to be contacted per javamail API. Do not set for this impl.
folder	"INBOX"	Name of the logical folder to retrieve from on the server.
port	"110"	TCP port for connecting to the server. Should be 110 for non-encrypted, 995 for ssl, or custom values as needed.
basedir	system temp dir	Location in which to save attachment files. Defaults to the temp directory as reported to java by the OS at runtime.
ssl	"0"	Determines whether an encrypted connection should be used. If "1", then other SSL-related settings will be observed.
mail.pop3.socketFactory.class	"javax.net.ssl.SSLSocketFactory"	Class name for an encrypted socket provider. Don't change unless you're using SSL and know what you're doing.
mail.pop3.socketFactory.fallback	"false"	If true, then a non-SSL socket will be provided if an SSL one cannot be created. Don't change unless you're using SSL and know what you're doing.
mail.pop3.port	port, above	Set automatically by this class. Not overridable in the current impl.
mail.pop3.socketFactory.port	port, above	Set automatically by this class. Not overridable in the current impl.

org.apache.commons.net.pop3.POP3Client
The POP3Client class implements the client side of the Internet POP3 Protocol defined in RFC 1939. All commands are supported, including the APOP command which requires MD5 encryption. See RFC 1939 for more details on the POP3 protocol.
Rather than list it separately for each method, we mention here that every method communicating with the server and throwing an IOException can also throw a {@link org.apache.commons.net.MalformedServerReplyException}, which is a subclass of IOException. A MalformedServerReplyException will be thrown when the reply received from the server deviates enough from the protocol specification that it cannot be interpreted in a useful manner despite attempts to be as lenient as possible.
