Hi forum, i have folloing problem: every outgoing mail should get a disclaimer message using smtp event sink. a special config is needed, because there is a problem with MAPI Clients. for this config i need two virtual servers - one is forwarding to the second and on this server i register the smtp event sink. i use this configuration virtualSMTP-Server 1 This Server transmitmessages to virtual server 2. outgoing messagesare sent to127.0.0.1 Port 26 virtual SMTP-Server 2 For this server is the script registered. listen on port 26.takes connections fromVSMTP1 and forwards messages to the internet. usingsmarthost or dns SMTP-Connector takes care that virtual server 1 is used first additional problem is that i have no registered internet domain as test environment and i have no ISP smarthost. In the properties of the virtual server i cannot resolve the FQDN, also if i use internal mail.domain.local name - smarthost is not set. In the eventvwr i have 7004 and 7010 events(504 need to authenticate first), and there is no outgoing mail received. i gave already exchange domain servers the "send as" right like recommended for 7004 and 7010 errors and i installedbulletin update like recommended inthe knowledgebase . i use 2003 with SP 2 i think, how do i say to the event sink server that he should use dns for forwarding? how do i make outgoing mail transport? hope someone has the right information - thanks
