sorry guys, i can see you are not getting my question here, i mean, if you are using MSExchange, you can configure your clients to log on from anywhere in the World as long as they are connected on the internet thus thats WebAccess im talking about, you configure certain ports and you can download mail from your server any place in the world , WebAccess, so i want to ask if HMailserver can provide that functionality where i can be able to configure my serve so that i can let my clients log on from anywhere in the world using any email client.
According to http://en.wikipedia.org/wiki/Outlook_Web_Access
OWA is webmail for Exchange server. So either your question was not correct or you don't realize that Microsoft's WebAccess thing is called webmail in any other setup.
If you want to use any email
client with hMailServer, you are free to do that. POP3, IMAP and SMTP communication protocols are standard. Any normal email client can use them. POP3, IMAP and SMTP ports are open by default in hMailServer. If they are not open in your setup, then you closed them yourself and you should know how to reopen them.
