Slightly wrong track.
Email and FTP are very different.
SoftPAC will send emails no trouble, and the cool thing is, because its a Windows PC, it already has the certificates installed.
So, its safe to say, when it comes to sending emails, SoftPAC just works.
(Just use the PAC Control commands as per Forum examples or the example code in the PAC Control Command Guide).
FTP is File Transfer Protocol. As you see and heard from Mary (and form 2020), SoftPAC does not support that mem-map area, but there are some work arounds (as Mary pointed out).
