That's a good question. There is an API gateway running on the Novell server. With regard to the Groupwise SMTP agent, (Gateway to Internet Mail) I would have initially assumed that once the directories had been replicated, I would be able to use Novell box (not the case). The API gateway loaded on the novell server facilitates DirSync with Exchange and facilitates messaging between the two systems. As for sending SMTP mail from Exchange(different address space) out the Novell Groupwise internet Agent Gateway, I have accomplished this. The problem is return mail. The mail when replied to does not get routed back to the Exchange server. I may have to set up rules on the novell environment for this domain. The documentation from MS is decent, zero support from Novell on this process and of course they have thier own connector that resides on the Novell server that has a giant security hole. I'm dying for better documentation or if someone has done this before. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
