Method Detail

forward

public ReversePath forward(ReversePath reversePath,
                           Recipient originalRecipient)

Returns a reverse path which can be used in the forwarded mail.

Parameters:

reversePath - the reversePath which with our server received the mail to be forwarded

originalRecipient - the mail was received for this recipient, which recipient address is configured to forward mail to another address.

reverse

public Recipient reverse(Recipient srsRecipient)
                  throws InvalidSrsException

Throws:

InvalidSrsException

getLocalDomains

public RemotePartSpecification getLocalDomains()

Category:

GETSET

setLocalDomains

public void setLocalDomains(RemotePartSpecification localDomains)

Sets the domains which authorize this server to send mail in their name using the SPF DNS record. Reverse paths from these domains will not be rewritten. If not set, than it is assumed that the domain of any accepted mail authorizes this server to send mail in its name.

GETSET

getDefaultRemotePart

public RemotePart getDefaultRemotePart()

Category:

GETSET

setDefaultRemotePart

public void setDefaultRemotePart(RemotePart defaultRemotePart)

Sets the remote part used in the rewritten reverse path for those recipients whose domain does not appear in the localDomains field, but for some reason mails to those domains are accepted. For example mail sent to the global Postmaster address has no domain at all.

getSecretKey

public String getSecretKey()

setSecretKey

public void setSecretKey(String secretKey)

Sets the secret key as a HEX string. It should be long enough to be hard to recover with a brute force attack.

public void setSecretKeyString(String secretKey)

Sets the secret key by encoding the supplied String with UTF-8 to get the key bytes.
