With cPanel a user could log into their webmail and get their email server settings. I see this is available as a module in Virtualmin. Could it be added to Usermin?
Insofar as cPanel uses Roundcube for webmail, I don’t think that a user can see within Roundcube itself what the email server settings are. Or am I mistaken about this?
I think that Usermin is really intended for end-users who shouldn’t need (or don’t want) to worry about what their email server settings are
