9.3.6.1 Greeting Pause
Mail servers send a Greeting Message to the sending mail server. An uncorrupted mail serv-
er will deliver more SMTP commands after it gets this message.
Spam mail servers
don’t wait for this message and deliver the mail immediately. The mail
relay drops e-mails if the Greeting Message rule has been ignored.
You can define mail servers
that don’t have to wait for the Greeting Message. Use the
Edi
t
button beneath
Define Exceptions
and enter the
IP address
or the
host name
of the mail
server.
9.3.6.2 Recipient flooding
Refers to the sending of mails to a lot of recipients, at which the recipient addresses are
composed randomly. After a defined number of failed delivery attempts a pause of 1 second
will be made.
This slows down the query of e-mail addresses and it will be inefficient for the address collec-
tor.
9.3.6.3 Limit max number of recipients
Define a maximum number of recipients inside an e-mail.
9.3.6.4 Limit connections
Limits the simultaneous connections to your firewall per second.
You can define mail servers by IP address or host name which should be excluded from this
limit.
9.3.6.5 Rate Control
Limits the simultaneous connections from one server in a interval of one minute (default).
Exceptions can be defined.
You can define mail servers by IP address or host name which should be excluded from this
limit.
