dracd
saves the sender's IP in a database.
For the period determined by DRACD_RELAYTIME
, the eMail Server grants relay access to the sender with this IP.
Afterwards, a new authentication is required. POP clients can do this by prompting a mail retrieval. For IMAP clients,
dracinterval
can be used to prompt dracd
to look for an open connection so that
DRACD_RELAYTIME
does not time out.
