Active Directory/Windows Authentication
MailEnable Integrated Authentication allows you to use Active Directory/Windows
Authentication as well as MailEnable's inbuilt authentication. It also allows you
to have mailboxes created automatically as users successfully authenticate using
Secure Sockets Layer (SSL) support for SMTP, POP and IMAP Protocols
MailEnable Professional and Enterprise editions allow mail clients to connect to the server over
SSL, ensuring that mail communications between the mail client and MailEnable are encrypted.
Usually passwords are sent in clear text over the network. This means that the data
stream can be intercepted and read, however, APOP encrypts the password before it
sends it and this changes every time the user logs on - so even if the encrypted
password is intercepted by a third party, it cannot be used to log-on.
POP Before SMTP Authentication
Requires users to access their mailbox first before being authenticated to send
messages through MailEnable. This process means that users have to be verified before
being able to access the mail server to send. This is provided as an alternative
to users whose email clients do not support SMTP authentication.
Secure Password Authentication (NTLM Support)
Mail users with Microsoft Outlook or Outlook Express can select the option to use
Secure Password Authentication when authenticating against the MailEnable Server.
This effectively provides a higher level of password encryption when clients authenticate
SMTP authentication allows users outside of a domain to use that domain as their
SMTP server when sending mail. SMTP Authentication requires that users log in with
a valid username and password for that domain before sending mail. SMTP authentication
prevents people relaying through the server to send spam.
CRAM MD5 Authentication
CRAM-MD5 is a challenge-response algorithm based on HMAC-MD5.
