How to setup SMTP Server Authentication settings for all users

[dshad]

Hello everyone,

I'm using Roundcube through my Synology DS411j.

What I'd like to do is have 1 settings for all my users.  I'm using SMTP Relay from DYN.

Server is: outbound.mailhop.org
Port is : 2525

It requires authentication username and password.

What I would like is to setup my Dyn username and password for all my Synology users so they can send mail.  Tried to do this:

Replace:

$rcmail_config['smtp_user'] = '%u';

With:

$rcmail_config['smtp_user'] = 'username';

And do the same with password but when I logged in, I noticed that the 2 fields were blank.

So how do I do that?
