I am currently consulting for a small retailer. They have been using
an online email service provider for the past few years to blast
personalized emails to their customers (opt-in, and 100-200 thousand
emails at a time). They have asked me to see if we can install an
email server in house to accomplish the same thing and eliminate the
monthly costs. I am fairly familiar with Linux/Unix and with
databases (mysql and postgresql). I have not done anything with
Sendmail or Postfix but feel comfortable following the documentation.
I have also ordered the two books that I could find on Postfix.
My questions are: has anyone used Postfix for this purpose? Do the
online ESP's develop their own email servers? Does any of them use
Sendmail, Postfix or qmail?
Thanks in advance for any information or links.
