Serverless Sending (iFAX)
If there is the [Send via Server] setting for an address in the address book and the setting is
set to [OFF], the fax is sent directly to the address specified as the destination.
If it is set to [ON], the fax is sent to the mail server that is set in the user mode.
If the destination address is described in IP address format like ifax@[172.22.10.82], the fax
is sent to this IP address.
It is specified in RFC2821 that e-mail addresses in IP address format should be put in
brackets “[ ]”.
When describe the e-mail address of the IP address, you should enclosed by brackets such
as [123.255.37.2].
In the case of IPv6, it is ifax@[IPv6:X:X:X:X:X:X:X:X]
In a security-critical environment, a layer 3 switch and the like may be used to set SMTP so
that it cannot exceed the domain even in an IP reachable environment.
If a fax is accidentally sent to a mail server in a different domain, the reception may be
rejected depending on the setting of the mail server.
Use of serverless sending requires prior consultation with the system manager.

Data Size Limit
During serverless sending with COPIER > OPTION > USER > IFAX-SZL in the service mode
set to "1," if an e-mail exceeds the data size limit ([Maximum Data Size for Sending] in the
user mode), it can be sent divided into parts, or it can be sent without causing a sending error
even though it exceeds the limit.
IFAX-SZL is "1" by default.
How to Set [Send via Server] to [OFF]
The [Use Send via Server] setting is set to [ON] by default.
To set the setting to [OFF], follow the following steps.
Setting/Registration > Function Settings > Send > E-Mail/I-Fax Settings > Use Send via
Server > ON
Setting/Registration > Set Destination > Register Destinations > I FAX > Send via Server >
OFF
