Hi,

I get "fatal: unknown service: smtp/tcp" in a non-chroot environment.

However, the platform is a very much stripped-down environment (OpenBSD
3.5), so it could be that something essential is missing
(/etc/services; /etc/protocols are present - something else that would be
obvious?)

Some locations are a bit non-standard, but postfix starts up (without
warnings) without me having tinkered with postfix-script or even some source
code.

===
# /usr/local/sbin/postconf -n
alias_database =
alias_maps =
command_directory = /usr/local/sbin
config_directory = /etc/postfix
daemon_directory = /usr/local/libexec/postfix
disable_mime_input_processing = yes
header_checks = regexp:/etc/postfix/header_checks
inet_interfaces = 127.0.0.1
local_recipient_maps =
local_transport = error:Local mail delivery disabled.
mail_owner = postfix
mailq_path = /usr/local/sbin/mailq
mime_header_checks =
mydestination =
myhostname = themailhost
mynetworks =
mynetworks_style = host
nested_header_checks =
queue_directory = /var/mailqueue
relay_domains =
relayhost = [192.168.1.130]
sendmail_path = /usr/local/sbin/sendmail
setgid_group = postdrop
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
transport_maps = hash:/etc/postfix/transport
virtual_transport = error:Virtual mail domains disabled.
===

as I said, without chroot:
# service type private unpriv chroot wakeup maxproc command + args
# (yes) (yes) (yes) (never) (100)
smtp inet n - n - - smtpd
smtp unix - - n - - smtp

The error occurs after I have successfully submitted a message with sendmail
-bs, when postfix tries to deliver it:

postfix/pickup[17928]: 6D4DFA0: uid=0 from=<sender>
postfix/cleanup[7119]: 6D4DFA0: message-id=<msgid>
postfix/qmgr[28579]: 6D4DFA0: from=<sender>, size=445, nrcpt=1 (queue active)
postfix/smtp[8479]: fatal: unknown service: smtp/tcp
postfix/qmgr[13241]: warning: premature end-of-input on private/smtp socket while reading input attribute name
postfix/master[28478]: warning: process /usr/local/libexec/postfix/smtp pid 8479 exit status 1
postfix/master[28478]: warning: /usr/local/libexec/postfix/smtp: bad command startup -- throttling
postfix/qmgr[13241]: warning: private/smtp socket: malformed response
postfix/qmgr[13241]: warning: transport smtp failure -- see a previous warning/fatal/panic logfile record for the problem description

Anything obvious (or not that obvious)?

thanks & hand
