Your app needs to have a card or substack where the customers can add their mail account login data and the server ip or name and all the other information they would enter when adding an email account to their e-mail client.

Those people would also run into trouble if they switch to another e-mail client or if they get a new computer where they have to setup the e-mail client again.
This is not an email problem per se, but rather the problem that users are not doing proper password management.

What exactly did you want to do?
Use the server to send e-mails  to internal accounts on that server?

Or did you want to use that server as a relay server to send emails to external e-mail addresses? To do that you normally need an e-mail account on that server and your account needs to have the right to send external e-mails and you need to have to authenticate on that server when sending the e-mails to external users.

tsNet behaves like an e-mail client. If the customer now there e-mail credentials and other information for setting up an e-mail client and if your app allows to enter those information, then tsNet will work without a problem.
Maybe with one exception. If the server only allows 2FA for the e-mail clients, then tsNet needs to support this. Maybe this is already the case, maybe not.
This is a question Charles Warwick or Livecode Support could answer

The problem there is that some email clients (like gMail) limit the size of the message body that can be generated from their APIs. If you use revMail with someone with gMail as their default mail, the message body can only be about 2500 characters (or maybe 5000, I forget the exact limit).
