I don't know this service, but I'd suggest a visit to their website to find the settings. If they don't give the ones for Android, copy the ones for MS Outlook. You may need to play around with the security settings - especially whether it requires authentication before sending and whether it wants SLS/TLS, something else, or nothing at all. There's a reasonable chance the port numbers will be the default ones, so you may be OK there.
If there's no information from the supplier, have a look at the settings you use elsewhere and adapt those (I'm assuming you already have the service set up on a PC or similar).
