Hi Haithm,
You should contact your mail provider since the socket error likely is caused by a connexion refused. Mail servers often enforce quotas on mail clients to prevent abusive use of automated mailing systems. You might also simply be using wrong credentials or be blocked by a firewall.
To setup a default MAPI profile, open a session in windows using the same credentials as your PlanetPress services, then create a default mail profile in MS Outlook.
If you are still experiencing issues after looking into this, I recommend you open a tech support ticket from our website, or at 1-866-348-5863.
Thanks. Regards,
Olivier
