Hi,
I just encountered a wierd thing (debian-11 stable, postfix-3.5.6-1+b1).
I ran:
$ postconf -df proxy_read_maps
proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps
$virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains
$relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps
$recipient_canonical_maps $relocated_maps $transport_maps $mynetworks
$smtpd_sender_login_maps $sender_bcc_maps $recipient_bcc_maps
$smtp_generic_maps $lmtp_generic_maps $alias_maps $smtpd_client_restrictions
$smtpd_helo_restrictions $smtpd_sender_restrictions
$smtpd_relay_restrictions $smtpd_recipient_restrictions
$address_verify_sender_dependent_default_transport_maps
$address_verify_sender_dependent_relayhost_maps
$address_verify_transport_maps $fallback_transport_maps
$lmtp_discard_lhlo_keyword_address_maps $lmtp_pix_workaround_maps
$lmtp_sasl_password_maps $lmtp_tls_policy_maps $mailbox_command_maps
$mailbox_transport_maps $postscreen_discard_ehlo_keyword_address_maps
$rbl_reply_maps $sender_dependent_default_transport_maps
$sender_dependent_relayhost_maps $smtp_discard_ehlo_keyword_address_maps
$smtp_pix_workaround_maps $smtp_sasl_password_maps $smtp_tls_policy_maps
$smtpd_discard_ehlo_keyword_address_maps $smtpd_milter_maps
$virtual_gid_maps $virtual_uid_maps
And I thought I'd recursively expand all the items,
but I didn't get what I expected. Here are the non-empty
items individually expanded (redacted):
local_recipient_maps = proxy:unix:passwd.byname hash:/etc/aliases,
nis:mail.aliases
mydestination = hostname.localdomain, localhost.localdomain, localhost
relay_domains = hostname.localdomain, localhost.localdomain, localhost
mynetworks = 127.0.0.0/8 a.b.c.d/32 [::1]/128 [a:b:c:d::e]/128 [fe80::]/64
alias_maps = hash:/etc/aliases, nis:mail.aliases
So I was expecting all of that concatenated:
proxy_read_maps = proxy:unix:passwd.byname hash:/etc/aliases, nis:mail.aliases
hostname.localdomain, localhost.localdomain, localhost
hostname.localdomain, localhost.localdomain, localhost
127.0.0.0/8 a.b.c.d/32 [::1]/128 [a:b:c:d::e]/128 [fe80::]/64
hash:/etc/aliases, nis:mail.aliases
But instead I saw:
$ postconf -xdf proxy_read_maps
proxy_read_maps = all127.0.0.0/8 a.b.c.d/32 [::1]/128
[a:b:c:d::e]/128 [fe80::]/64 hash:/etc/aliases, nis:mail.aliases
It looks like the default value of inet_interfaces or
inet_protocols "all" (neither of which belong there),
immediately followed (with no intervening space)
by the default values of mynetworks and alias_maps.
Where did the "all" come from?
What happened to the default values of local_recipient_maps,
mydestination and relay_domains?
This happens with or without the -f option.
Does it happen with a non-Debian-packaged version?
If anyone can explain this behaviour, or the error in my
expectations, that would be great.
Without the -d option for defaults, the output is perfect.
cheers,
raf
