I am new to Postfix and am wondering something about Postfix. Currently, all our email comes into 2 Proofpoint appliances. Email that passes through goes straight to the Groupwise Internet Agent (GWIA), which distributes the email where it needs to go within our email system.
We are switching to a cloud email system. In the transition period, we'd like all email to go to both places, but not forwarded. Is it possible to use Postfix in the middle somewhere to send email to two different locations? Thanks in advance, Scott Fitzhugh
