getAttribute

public java.lang.Object getAttribute(java.lang.String key)

Description copied from interface: MailetContext

Returns the mailet container attribute with the given name, or null if there is no attribute by that name. An attribute allows a mailet container to give the mailet additional information not already provided by this interface. See your server documentation for information about its attributes. A list of supported attributes can be retrieved using getAttributeNames.

The attribute is returned as a java.lang.Object or some subclass. Attribute names should follow the same convention as package names. The Java Mailet API specification reserves names matching java.*, javax.*, and sun.*

Specified by:

getAttribute in interface MailetContext

Parameters:

key - - a String specifying the name of the attribute

Returns:

an Object containing the value of the attribute, or null if no attribute exists matching the given name

setAttribute

public void setAttribute(java.lang.String key,
                         java.lang.Object object)

Description copied from interface: MailetContext

Binds an object to a given attribute name in this mailet context. If the name specified is already used for an attribute, this method will remove the old attribute and bind the name to the new attribute.

Attribute names should follow the same convention as package names. The Java Mailet API specification reserves names matching java.*, javax.*, and sun.*.

Specified by:

setAttribute in interface MailetContext

Parameters:

key - - a String specifying the name of the attribute

object - - an Object representing the attribute to be bound

removeAttribute

public void removeAttribute(java.lang.String key)

Description copied from interface: MailetContext

Removes the attribute with the given name from the mailet context. After removal, subsequent calls to getAttribute(java.lang.String) to retrieve the attribute's value will return null.

Specified by:

removeAttribute in interface MailetContext

Parameters:

key - - a String specifying the name of the attribute to be removed

getAttributeNames

public java.util.Iterator getAttributeNames()

Description copied from interface: MailetContext

Returns an Iterator containing the attribute names available within this mailet context. Use the getAttribute(java.lang.String) method with an attribute name to get the value of an attribute.

Specified by:

getAttributeNames in interface MailetContext

Returns:

an Iterator of attribute names

bounce

public void bounce(Mail mail,
                   java.lang.String message)
            throws javax.mail.MessagingException

This generates a response to the Return-Path address, or the address of the message's sender if the Return-Path is not available. Note that this is different than a mail-client's reply, which would use the Reply-To or From header. This will send the bounce with the server's postmaster as the sender.

Specified by:

bounce in interface MailetContext

Parameters:

mail - - the message that is to be bounced and sender to whom to return the message

message - - a descriptive message as to why the message bounced

Throws:

javax.mail.MessagingException

bounce

public void bounce(Mail mail,
                   java.lang.String message,
                   MailAddress bouncer)
            throws javax.mail.MessagingException

This generates a response to the Return-Path address, or the address of the message's sender if the Return-Path is not available. Note that this is different than a mail-client's reply, which would use the Reply-To or From header. Bounced messages are attached in their entirety (headers and content) and the resulting MIME part type is "message/rfc822". The attachment to the subject of the original message (or "No Subject" if there is no subject in the original message) There are outstanding issues with this implementation revolving around handling of the return-path header. MIME layout of the bounce message: multipart (mixed)/ contentPartRoot (body) = mpContent (alternative)/ part (body) = message part (body) = original

Specified by:

bounce in interface MailetContext

Parameters:

mail - - the message that is to be bounced and sender to whom to return the message

message - - a descriptive message as to why the message bounced

bouncer - - the address to give as the sender of the bounced message

Throws:

javax.mail.MessagingException

Specified by:

log in interface MailetContext

Parameters:

message - the message to pass to the Mailet logger

t - the Throwable to be logged

addUser

public boolean addUser(java.lang.String userName,
                       java.lang.String password)

Deprecated. we deprecated this in the MailServer interface and this is an implementation this component depends already depends on a UsersRepository: clients could directly use the addUser of the usersRepository.

Adds a user to this mail server. Currently just adds user to a UsersRepository.

Specified by:

addUser in interface JamesMBean

Specified by:

addUser in interface MailServer

Parameters:

userName - String representing user name, that is the portion of an email address before the '@'.

password - String plaintext password

Returns:

boolean true if user added succesfully, else false.

getSMTPHostAddresses

public java.util.Iterator getSMTPHostAddresses(java.lang.String domainName)

Performs DNS lookups as needed to find servers which should or might support SMTP. Returns an Iterator over HostAddress, a specialized subclass of javax.mail.URLName, which provides location information for servers that are specified as mail handlers for the given hostname. This is done using MX records, and the HostAddress instances are returned sorted by MX priority. If no host is found for domainName, the Iterator returned will be empty and the first call to hasNext() will return false.

Specified by:

getSMTPHostAddresses in interface MailetContext

Parameters:

domainName - - the domain for which to find mail servers

Returns:

an Iterator over HostAddress instances, sorted by priority

Since:

Mailet API v2.2.0a16-unstable

See Also:

org.apache.james.DNSServer#getSMTPHostAddresses(String)

storeMail

public void storeMail(MailAddress sender,
                      MailAddress recipient,
                      javax.mail.internet.MimeMessage msg)
               throws javax.mail.MessagingException

Deprecated. since 2.2.0 look at the LocalDelivery code to find out how to do the local delivery.

This method has been moved to LocalDelivery (the only client of the method). Now we can safely remove it from the Mailet API and from this implementation of MailetContext. The local field localDeliveryMailet will be removed when we remove the storeMail method.

Specified by:

storeMail in interface MailetContext

Parameters:

sender - - the sender of the incoming message

recipient - - the user who is receiving this message (as a complete email address)

msg - - the MimeMessage to store in a local mailbox

Throws:

javax.mail.MessagingException - - if the message fails to parse
