<Allow SSL (POP)> in the E-mail/I-Fax setting to ‘Off’. (See Chapter 3, “Setting

up the Machine for Your Network Environment,” in the System Settings Guide.)

Remedy 3 Disable POP before SMTP by setting <POP Authentication before Send> in the

E-mail/I-Fax setting to ‘Off’. (See Chapter 3, “Setting up the Machine for Your

Network Environment,” in the System Settings Guide.)

Chapter 3, “Setting up the Machine for Your Network Environment,” in the

System Settings Guide.)
