Hi,
In /etc/aliases of projecthost.my.domain I have
teamfoo:
localcopy
j...@example.com
b...@domain.tld
john@some.where
Bob checks SPF on incoming messages.
Now sends Alice an e-mail to Team Foo. Domain Alice has SPF records.
That e-mail arrives the machine with the teamfoo alias.
Postfix does what it is supposed to do and e-mails the team members.
Bob's mailserver rejects and sends to Alice
<b...@domain.tld> (expanded from <team...@projecthost.my.domain>): host
mail.domain.tld[BOB.IP.ADD.RES] said: 550-[SPF] MY.IP.ADD.RES
allowed to send mail from alice.domain. Please 550 see
http://www.openspf.org/Why?scope=mfrom;identity=alice@alice.domain;ip=MY.IP.ADD.RES
(in reply to RCPT TO command)
In the year 2017 is that all correct behaviour.
Several years earlier was a team alias best pratice.
Now I'm looking for a successor.
I think the right approach is
* recieve the e-mail
* rewrite some headers
** the Alice From should go into Reply To
** new From is team...@projecthost.my.domain
* send the message of Alice to the foo team members
But I'm lost and in need for advice.
What I did so far
* a websearch on "aliases SPF"
* tried to understand which Postfix virtual covers my needs
* /etc/alias with 'teamfoo: |/some/script'
* wondered if it is the (good?) old procmail that I need
The /some/script
#!/bin/bash
mailx -s teamFoo \
localcopy \
j...@example.com \
b...@domain.tld \
john@some.where \
