An e-mail session is when an e-mail client and e-mail server (or two e-mail servers) connect
through the Zyxel Device. Select how to handle concurrent e-mail sessions that exceed the
maximum number of concurrent e-mail sessions that the anti-spam feature can handle. See
the chapter of product specifications for the threshold.
Select Forward Session to have the Zyxel Device allow the excess e-mail sessions without any
spam filtering.
Select Drop Session to have the Zyxel Device drop mail connections to stop the excess e-mail
sessions. The e-mail client or server will have to re-attempt to send or receive e-mail later
when the number of e-mail sessions is under the threshold.
