protected Collection<String> resolveTXTRecords(String ip)

Return a Collection which holds all TXT records for the ip. This is most times used to add details for a RBL entry. This implementation always returns an empty Collection. Sub-classes may override this.

Parameters:

ip -

Returns:

txtRecords

doRcpt

public HookResult doRcpt(SMTPSession session,
                MailAddress sender,
                MailAddress rcpt)

Description copied from interface: RcptHook

Return the HookResult after run the hook

Specified by:
