Hi, I wanted to try and use a fax back service - these services typically send a fax after you send a mail with the fax number as part of the address
so what I wanted was to make a fax number field
I need to use this as the address and add the fax service domain to create a full email address to send to
is this possible?
for instance they enter 18005551234 and the mail gets sent to email@example.com
