This page lets you configure the SMTP server component of VPOP3. This is how users send mail (either outgoing or internal), and also how VPOP3 receives incoming SMTP messages.
In VPOP3 Enterprise, you can create multiple SMTP servers with different settings for instance, to allow SSL connections for local users using the older SMTPS (port 465) encryption method (e.g. Microsoft Outlook/Outlook Express), while still allowing unencrypted connections or the newer TLS encryption for incoming SMTP feeds.
