Аlerts triggering e-mails

Dear colleagues,

We have Solution Manager 7.1 SP4. It is used to monitor NW 7.31 Business Process Management application in productive usage deployed on Java only system. Now we are able to monitor predefined Business Process Management metrics as described in 4.4.8 SAP CE/BPM-Specific Monitoring https://websmp204.sap-ag.de/~sapidb/011000358700000064532012E

Alerts are enabled for process and task instances and we can monitor them in Alerts inbox.

E-mail notifications are enabled in Solution Manager (details: http://scn.sap.com/message/13302866#13302866)

What we are still missing is e-mails triggered by alerts.

Following Basic configuration document https://websmp203.sap-ag.de/~sapidb/011000358700000482292011E/SM71_Configuration.pdf I found that we have to do it in Basic configuration->configure SAPconnect 3.3 so I have specified mail host, port, domain, SMTP active (screenshot below).

Would you please give me some hints or document how to achieve it?
