Summary     : User configurable relay-only Mail Transfer Agent (MTA)
Description :

(including the CRAM-MD5 and NTLM SASL mechanisms) and the StartTLS SMTP
extensions.

So these are ESMTP features:

 * requires no administration privileges
 * individual user configuration
 * sendmail command line compatible
 * supports the AUTH SMTP extension, with the CRAM-MD5 and NTLM SASL
   mechanisms
 * support the StartTLS SMTP extension
 * does not receive mail, expand aliases or manage a queue
