memfilesizelimit

Set the maximum file size that can be

10 (MB)

All models.

<MB_integer>

buffered to memory for virus scanning.

 

 

 

The maximum file size allowed is 10% of the

 

 

 

FortiGate RAM size. For example, a

 

 

 

FortiGate unit with 256 MB of RAM could

 

 

 

have a threshold range of 1 MB to 25 MB.

 

 

 

Note: For email scanning, the

 

 

 

memfilesizelimit refers to the final size of the

 

 

 

email after encoding by the email client,

 

 

 

including attachments. Email clients may use

 

 

 

a variety of encoding types and some

 

 

 

encoding types translate into larger file sizes

 

 

 

than the original attachment. The most

 

 

 

common encoding, base64, translates 3

 

 

 

bytes of binary data into 4 bytes of base64

 

 

 

data. So a file may be blocked or logged as

 

 

 

oversized even if the attachment is several

 

 

 

megabytes less than the memfilesizelimit.

 

 

port

Configure antivirus scanning on a

143

All models.

<port_integer>

nonstandard port number or multiple port

 

 

numbers for SMTP. You can use ports from

 

 

 

the range 1-65535. You can add up to 20

 

 

 

ports.

between 1 and the total memory size. Enter

 

 

 

0 for no limit (not recommended).
