Fresh install using the .bin/setup wizard on SLES11 SP2. I am testing a few things and 1 is invites. I enter an external user and alfresco appears to send the invite (without error) but the user never gets the invite. I have followed http://wiki.alfresco.com/wiki/Outbound_E-mail_Configuration (port 587) and restarted alfresco but still, invite not received. How do you config alfresco to send external invites?
