Postfix MTA (Mail Transfer Agent)

• Need a high performance, secure and easy to configure MTA (Mail Transfer Agent)

• Postfix made available free from IBM

  • Fastest OSS MTA available - uses pipeline architecture (When we tested it, we got 50 messages per second against about 3 messages per second for sendmail)
  • Regarded as highly secure (secure by design)
  • Easy to administer as is not as complex as other free alternatives such as Sendmail

• LDAP Directory enabled enabling unified user management
