If there is just one domain (realm) to which the user belongs, it is notified
from the SMTP server at the time of initial communication, and commu-
nication is automatically made using the domain name. Therefore, no do-
main name setting on this machine is not required. If there are two
domains or more to which the user belongs, however, specify the domain
name to which the user belongs.
If the POP server is different from the SMTP server, the POP server in-
forms the SMTP server that it has been logged in. Therefore, if the set
POP before SMTP time is too short, messages may not be sent.
If virus scanning software is used on the mail server, the binary division
feature may not be available. For details, contact your network adminis-
trator.
To receive binary divided e-mail messages, mail client software support-
ing divided reception is required. Depending on the mail client software
being used, it may not be possible to combine received e-mail messages
that have been divided.
