Hi,
we have got this problem with alfresco share:
When I use rule on folder with "send email" action and this rule is applied for example when user upload file, this uploading ends with error "error: email recipients were invalid".
Outbound email configuration is correct. Test message when alfresco starts is succesfully delivered. Daily recent activities mail is OK too. Users are synchronized with LDAP and every user has corrent email in profile.
Any idea or direction? THX
BTW: Alfresco is our first CMS and we have got about month experiences with.
