Hi, I am not sure if this is the right place to post this query? In case not please accept my apologies and have a big heart to ignore this post. We have been using iplanet exchange server for our Mail requirements along with Unified communications to have web access to our mails. However, iplanet version that we have does not support latest version of operating system that we have. i.e. Solaris 10 Update 9. We came to know about Oracle Communications messaging exchange server 7 U1. However, after going through documentation I am still not very clear on what all components we would require to be installed and their order of installation. All we need is a stand alone Messaging Exchange server along with http/web mail support. That is the only requirement we have. My basic understanding is that i would need to install directory server 11gR1 in any case. Do i need to have either Communications express or Convergence 2? If yes that would mean that i need to install a lot many more components like Web container (glassfish) & indexing , calendar server. Please let me know if my understanding is correct. Is messaging exchange server different from messaging server webmail server? If yes, then is that also a mandate to be installed. Essentially all i need is a mail server with GUI client support. Please guide me as to how should i go about it. Also, this would be a standalone configuration. Can you also please confirm if i can use normal file system for message store? I would appreciate your help and guidance on this. Thank you.
