I wants to use mt SME 7.51 as Email server and web server to host web site, please guide where to start.
SME by default has the email server and web server enabled.
Configure external DNS records to point the Domain name at your SME servers external IP.
Add users & then Configure your email clients to use the SME server mail server eg
for IMAP
www.yourdomain.com on ports 465 & 993 secure
Add an ibay, configure it for external access, and then add web content to the ...ibay/html folder, you can usually see this folder in Windows networking.
Please read the Manual which is linked at the top of these Forums for further details.
Also look at Server Manager, Review Configuration panel for details of mail server settings etc and there is also a server manager Email panel where you can configure aspects of email functionality eg enable IMAP secure local or external etc etc.
