I am making my own policy service:
userpolicy unix - n n - 0 spawn user=mail
argv=/usr/libexec/postfix/per-user-policy
Which is called in smtpd_recipient_restrictions with
check_policy_service.
Per the SMTPD_POLICY_README it accepts inputs then replies with actions
and an empty line.
Everything is working up to this point, emails are accepted.
I get the impression from the SMTPD_POLICY_README and the access.5 pages
that you can respond with multiple actions before ending with an empty
line. However in practice no matter what combinations of actions i try
only the first one works and all others are ignored.
Example:
action=prepend Custom-Header: Header-value
action=info Custom-Log=Log-value
action=dunno
[empty line]
In that case only the header is added and the log info is ignored. If i
switch the prepend and info lines then only the log info is saved but
the header is not added. One example of why i expect both to work is the
man page for prepend says: "When more than one PREPEND action executes,
the first prepended header appears before the second etc. prepended
header." I tried removing the info and just doing two prepends and still
only the first one works and the second one is ignored.
Am i doing something wrong? Missing something? Or did i misunderstand
and you can only have one action per policy response?
