Keywords and Variables

Description

Default

 

 

 

capacity <cap_int>

Use this command to set the maximum number of greylist items

varies

 

stored in the greylist database. New items causing the greylist

 

 

database to grow larger than the set capacity will overwrite the oldest

 

 

item.

 

 

<cap_int> is the maximum number of items in the greylist

 

 

database.

 

 

The default value and acceptable range varies by FortiMail model. To

 

 

display the currently set capacity, use the get as greylist

 

 

command.

 

 

To determine the available capacity range for your FortiMail model,

 

 

enter a question mark for the capacity value and execute the

 

 

command.

 

 

 

 

exempt {add delete}

Use this command to add or delete addresses from the greylist

 

<address>

exemption list.

 

 

<address> can be an email address, IP address, a subnet, or a

 

 

domain.

 

greylistperiod

Use this command to set the length of time the FortiMail unit will

20

<period_int>

continue to reject messages with an unknown to/from/IP. After this

 

time expires, any resend attempts will have the to/from/IP data added

 

 

to the greylist and subsequent messages will be delivered

 

 

immediately.

 

 

<period_int> is the greylisting period in minutes. Acceptable

 

 

values range from 1 to 120 minutes.

 

initial_expiry_period

Use this command to set the length of time after the initial message

4

<exp_int>

that the FortiMail unit will keep record of a message with an unknown

 

to/from/IP. If the mail server resends a message before the initial

 

 

expiry period expires, it will be accepted. If the message is received

 

 

after the initial expiry period, the FortiMail treats the delivery as new

 

 

and rejects the message with a temporary fail.

 

 

Note that both the greylist period and the initial expiry period are

 

 

calculated from the time the first message is received and a

 

 

temporary fail is returned. Consequently, a 20 minute greylist period

 

 

and a 4 hour initial expiry period will result on a 3 hours and 40

 

 

minutes window for delivery of the message to fulfill the greylist

 

 

requirements and be accepted.

 

 

<exp_int> is the initial expiry period in hours. Acceptable values

 

 

range from 4 to 24 hours.

 

ttl <ttl_int>

Use this command to set the greylist time-to-live (TTL) value. TTL

10

 

determines how long the to/from/IP data will be retained in the

 

 

FortiMail unit’s greylist. When the entry expires, it is removed and

 

 

new messages are again rejected until the sending server attempts

 

 

to deliver the message again.

 

 

<ttl_int> is the time to live in days. Acceptable values range

 

 

from 1 to 60 days.
