Configuration

Avira GmbH Avira AntiVir MailGate 58

Default for all parameters is:

A maximum (HighFillLevel) and minimum (LowFillLevel) threshold value

are defined for this purpose. As soon as the maximum value is reached, any other

emails are rejected with a temporary error message (SMTP Code 452: insufficient

system storage). Depending on the performance and load of the system, the

number of emails might slighty exceed the given threshold. By setting a valid

treshold value you specify at what level the incoming or outgoing queue is

“congested” or is “available”. New connections are not accepted until the number

of emails in the queue drops to the minimum value

(LowFillLevel) or below

this value.

On startup, each queue’s status is reset to “available”. If the number of emails in a

queue is greater or equal to the defined

HighFillLevel, the queue is considered

as “congested”. If the number of emails in a queue is less or equal to its

LowFillLevel, the queue is considered as “available”. If the number of emails in

a queue is less than the

HighFillLevel but larger than the LowFillLevel and

the queue’s previous state was “congested”, its state remain unchanged. To change

this status the number of emails has to drop to the

LowFillLevel again.

On a restart, Avira AntiVir MailGate will accept new emails regardless to the previous

state. The system does not recall a previous “congested” state of a queue.

When the set threshold value is reached, the postmaster is informed by SNMP

trap or email with the aid of the Notification Mechanisms function.

The number of emails counted will also contain those created by Avira AntiVir MailGate

itself.

The following statements are valid:

• The threshold value for both

HighFillLevel and LowFillLevel

is 0 (default).

• The threshold value for

HighFillLevel is greater than that for

LowFillLevel.

If invalid statements are made, Avira AntiVir MailGate will not start.

viruses and malware (in seconds).

Default:

1 2 ... 57 58 59 60 61 62 63 64 65 66 67 ... 122 123
