Some Sharp fax machines require a certain type of SMTP server in order to be able to send emails.

SMTP2GO provides an SMTP server that can authenticate senders based on their IP address, or their ‘from’ email address, meaning that it works with fax machines that are unable to send an SMTP username or password.

Two examples of SMTP setup procedures for popular Sharp fax machines are below:

Sharp UX-B800SE and UX-D1200SE Broadband Fax SMTP setup

Change the ‘Network Settings’ setting to your account’s SMTP server. You can see what this is by logging into your control panel, and UNCHECK  the box ‘POP before SMTP’. Try entering either port 2525, 8025, 587, or 25 as the outgoing SMTP port. Port 2525 is recommended.

Important: If your fax machine has a fixed IP address, then add that IP address to the Settings > IP Authentication page in your SMTP2GO control panel. If it does not have a fixed IP address, you will need to contact our Support team in order to enable authentication based on email address.

See a sample screenshot from the UX-B800SE fax below:

Please note that Gmail’s SMTP server doesn’t work, as it not only requires a username/password, but it also requires that SSL/TLS is used.

Please note: some fax machines may still have a problem sending – if this is the case, use the IP address of 43.228.184.6 or 103.47.204.4 as the SMTP server.
