antivirus service pop3 command keywords and variables
Keywords and
variables
Description Default Availability
memfilesizelimit
<MB_integer>
Set the maximum file size that can be
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.
10 (MB) All models.
port
<port_integer>
Configure antivirus scanning on a
nonstandard port number or multiple port
numbers for POP3. You can use ports from
the range 1-65535. You can add up to 20
ports.

uncompsizelimit

that can be buffered to memory for virus
scanning. Enter a value in megabytes
between 1 and the total memory size. Enter
0 for no limit (not recommended).
