# $localhost_name is the name of THIS host running amavisd
# (typically 'localhost'). It is used in HELO SMTP command
# when reinjecting mail back to MTA via SMTP for final delivery,
# and in inserted Received header field
$localhost_name = 'localhost';
...although the HELO name mismatch is not a reason why a DKIM validation would
fail, must be something else.
Btw, you don't need an independent amavisd instance for signing. This can be
accomplished also by using a policy bank and dedicating a port on which
amavisd would only sign mail and skip all other checks if appropriate.
For example, here is my amavisd entry which only receives fanout mail
from our mailing list manager (via Postfix), i.e. messages which have
already been checked and only need still to be signed:
$inet_socket_port = [10024,10028];
$interface_policy{'10028'} = 'NOCHECKS';
$policy_bank{'NOCHECKS'} = {
smtpd_greeting_banner =>
'${helo-name} ${protocol} ${product} NOCHECKS service ready',
originating => 1,
mynetworks_maps => [], # avoids loading MYNETS policy unnecessarily
os_fingerprint_method => undef,
penpals_bonus_score => undef,
bypass_decode_parts => 1,
bypass_header_checks_maps => [1],
bypass_virus_checks_maps => [1],
bypass_spam_checks_maps => [1],
bypass_banned_checks_maps => [1],
spam_lovers_maps => [1],
banned_files_lovers_maps => [1],
archive_quarantine_to_maps => [],
remove_existing_x_scanned_headers => undef,
remove_existing_spam_headers => undef,
forward_method => 'smtp:[127.0.0.1]:10025',
signed_header_fields => { 'Sender' => 1 },
};
