user configurable relay-only MTA - the regular MTA

 ESMTP is a user configurable relay-only Mail Transfer Agent (MTA) with a
 sendmail-compatible syntax. It's based on libESMTP supporting the AUTH
 (including the CRAM-MD5 and NTLM SASL mechanisms) and the StartTLS SMTP
 ESMTP does not receive mail, expand aliases or manage a queue but can deliver
 mail locally via an MDA.
 This package provides the regular MTA programs.
