This document is part of Hindustan times implementation document talking about Qmail Disclaimer Integration with QMAIL Second Instance

Concept

Disclaimer on Qmail is Added to the Second Instance so that only Out going mails to different domains are uploaded with Common Signature / Disclaimer. This can be done for multiple domains too.


Implementation process

  1. Implement Qmail-2 , i.e Second Qmail Instance
  2. Define Qmail-send and Qmail-smtpd daemons
  3. Define 2nd Qmail smtp port ( say 900)
  4. Install Qmail-qfilter , altermime and bglibs to satisfy the requirement.
  5. Define Multiple domain's text and HTML disclaimer
  6. Integrate Qmail's both the instances
