Redirect specific e-mail address sent to a user, to other email-recipients

Question

I'd like to know if it is possible to configure postfix to redirect to many email addresses (including the original recipient) instead of only one?

Here is my scenario: When an e-mail is:

Sent from: [email protected]

Addressed to: [email protected]

Result: redirect e-mail to [email protected] and deliver to the original recipient

The question is partly answered here: https://serverfault.com/questions/284702/redirect-specific-e-mail-address-sent-to-a-user-to-another-user

Answer 1

Use an alias like this:

user: user, user2

According to the local(8) man page:

When an address is found in its own alias expansion, delivery is made to the user instead.

So you don't get infinite recursion.

Answer 2

I fixed the problem with procmail.

Below is an example:

#Get the sender's bare email address from the first "From" line
FROM_=`formail -c -x"From " \
         | expand | sed -e 's/^[ ]*//g' -e 's/[ ]*$//g' \
         | awk '{ print $1 }'`

#Get the original subject of the email
#Discard superfluous tabs and spaces
#On some systems -xSubject: has to be -x"Subject: "
SUBJ_=`formail -c -xSubject: \
         | expand \
         | sed -e 's/  */ /g' \
         | sed -e 's/^[ ]*//g' -e 's/[ ]*$//g'`

#Whatever other recipes you'll use

:0
* ^From:.*infolist@([-a-z0-9_]+\.)*infohost\.infodom
# Avoid email loops
* ! ^X-Loop: myid@myhost\.mydom
{
  :0c:   #Preserve a copy of the email
  Infolist.mail
  :0fwh  #Adjust some headers before forwarding
  | formail -A"X-Loop: [email protected]" \
            -A"X-From-Origin: ${FROM_}" \
            -i"Subject: $SUBJ_ (fwd)"
  # Forward the email
  :0
  [email protected]
}
