address of the received mail must specify the IFAX.
2. To enable SMTP reception: User Tools > Machine Features > System Settings > File Transfer
> Reception Protocol

Even if the MX record on the DNS server includes the IFAX, mail cannot be received with

record of the DNS server, then either IMAP4 or POP3 is used, depending on the setting:

Features > Facsimile Features > E-mail Settings > SMTP RX File Delivery Settings)
