is rumored to have said:
Dear Team,
Following is the requirement,
If from address is a...@domain.com(our own domain) and if the subject
starts with "[abcd] then from address to be changed to d...@domain.com
(domain remians same) before delivering the mail to recipient.
Is this possible in Postfix?
Not without additional software. The ideal tool for this would be a
"Milter" such as milter-regex, MIMEDefang, or MailMunge. You could also
do it in a delivery agent using the pipe interface.
If you are delivering that mail locally, another place that you could do
that manipulation might be in a Sieve tool like Pigeonhole, which is
integrated with the Dovecot IMAP server.
